A novel hyperbranched polyyne (hb-DPP) with triphenylamine as the core, 2,5-dioctylpyrrolo [3,4-c]pyrrole-1,4 (2H,5H)-dione (DPP) as the connecting unit has been designed and synthesized by Glaser-Hay oxidative coupling reaction, which was characterized by IR, NMR, UV-vis, FL, and GPC. The polymer exhibits high molecular weight (Mw up to 6.55 104 Da) and is readily soluble in common organic solvents such as toluene, chloroform, tetrahydrofuran, N,N-dimethyl formamide and so on. The one- and two-photon absorption (TPA) properties have been investigated. The TPA cross section of the polymer was measured by open-aperture Z-scan experiment using 140 femtosecond (fs) pulse, and the TPA cross section for hb-DPP was determined to be 579 GM per repeating unit at wavelength of 800 nm. In etrahydrofuran, hb-DPP exhibits intense frequency up-converted fluorescence with the peak located at 584 nm under the excitation of 800 nm fs pulses. VVC 2009 Wiley Periodicals, Inc.

Novel polyphenylacetylene (P1) containing naphthalimides units in the side chain was designed and synthesized. The structure and properties of the polymer were characterized and evaluated by IR, NMR, UV, and PL. The measurements of sensing behavior to various halide anions, that is, F, Cl, Br, and I, reveal that the polymer is a ratiometric fluorescent chemosensors for fluoride ion. The polymer sensor shows spectral shifts and intensity changes in the presence of fluoride, in a wavelength-ratiometric and -colorimetric manner, which can detect fluoride concentrations in range of 10-100 lM at visible wavelengths. The obvious colorless-toyellow color change and blue-to-orange emission color change on the addition of fluoride ion are easily observed by naked eyes. It provides a feasible way to construct a ratiometric fluorescent chemosensors for fluoride ion. VVC 2009 Wiley Periodicals, Inc.

Three, novel, fluoranthene-based dyes, 2-cyano-3-(5-(7,12-diphenylbenzo[k]fluoranthen-3-yl)thiophen-2-yl)acrylic acid, 2-(5-((5-7,12-diphenylben-zo[k]fluoranthen-3-yl)thiophen-2-yl)methylene)-4-oxo-2-thioxothiazolidin-3-yl)acetic acid and 2-cyano-3-(4-(2-(7,12-diphenylbenzo[k]fluoranthen-3-yl)ethynyl) phenyl) acrylic acid, were synthesized for application as sensitizers in dye-sensitized solar cells. In each dye, the 7,12-diphenyl-benzo[k]fluoranthene moiety acted as lectron donor with phenyl and thiophene units as electron spacers and carboxylic acid as electron acceptor. Tuning of the HOMO and LUMO energy levels was conveniently accomplished by changing the spacer and acceptor moiety, as confirmed using electrochemical measurements. Maximum solar energy:electricity conversion efficiency was 4.4% under AM 1.5 solar simulator (100 mW cm 2) for 2-cyano-3-(5-(7,12-diphenylbenzo[k]fluoranthen-3-yl) thiophen-2-yl)acrylic acid. The results suggest that dyes based on fluoranthene donor are promising candidates for high performance, dye-sensitized solar cells.

Two carboxylated cyanine dyes, 3-butyl-2-[3-(1-butyl-5-carboxy-1,3-dihydro-3,3-dimethyl-2H-indol-2-ylidene)-1-propen-1-yl]-1,1-dimethyl-7-[1-[2-[6-(4-morpholinyl)-1,3-dioxo-1H-benz[de]isoquinolin-2(3H)-yl]ethyl]-1H-1,2,3-triazol-4-yl]-1H-Benz[e]indolium iodide (A), 2-[5-(1-butyl-5-carboxy-1,3- dihydro-3,3-dimethyl-2H-indol-2-ylidene)-1,3-pentadienyl]-3-ethyl-1,1-dimethyl-1H-Benz[e]indolium iodide (B), have been prepared and their photophysical and electrochemical properties have been investigated. A, B and their mixtures (AB) were used as sensitizers in nanocrystalline TiO2 solar cells to improve photoelectric conversion efficiency. It was found that the solr cell sensitized with A3B1 (molar ratio: A:B=3:1) generated a high power conversion efficiency of 3.0% under AM1.5G illumination (100mWcm−2), indicating that co-sensitization is a promising method to improve the photoelectrical properties of dye-sensitized solar cells.

A novel organic cyanine dye containing triphenylamineebenzothiadiazole dyad has been synthesized and applied successfully to sensitization of nanocrystalline TiO2-based solar cell. Their absorption spectra, electrochemical, and photovoltaic properties were studied. Upon adsorption on a TiO2 electrode, the absorption spectra of the cyanine dye are all broadened at both the red and blue spectral ends relative to its respective spectra in acetonitrile and ethanol mixture solution. An overall conversion efficiency of 7.62% (Jsc¼22.10 mA cm 2, Voc¼0.54 V, ff¼0.48) is achieved under irradiation with 75 mWcm 2 white light from a Xe lamp.

Two novel near-infrared absorbing perylene imide derivatives (I and II) ith benzo[e]indole were designed and synthesized as sensitizers for dye-sensitized solar cells (DSSCs), and their structures were characterized by 1H NMR, 13C NMR, FT-IR, UV-vis, MS-ESI spectra, etc. The absorption spectra, electrochemical and photovoltatic properties of I and II were extensively investigated. Two perylene dyes have wide absorption bands with high molar extinction coefficients over the entire visible spectrum. Electrochemical properties indicated that the electron injection process from the excited dye molecule to TiO2 conduction band was energetically permitted. However, the preliminary photophysical and photoelectrochemical measurements show that the two perylene dyes have lower overall conversion efficiency on DSSCs application, although they have broad and intense absorption spectra in the visible region (up to 800 nm). This may be that the perylene imide group, which contains strong electron-withdrawing nature has effect on the polarity of the whole molecule, resulting in the unbeneficial transferring direction of photo-generated electrons, which decreases the overall photocurrent performance.

Perylene (Py)-containing polyacetylenes with different skeleton structures [HC¼C(C6H4)CO2 Py]n (P1), [HC¼C(CH2)8CO2 Py]n (P2), and {[(C6H5) C¼C(CH2)9NH2] co [(C6H5)C¼C(CH2)9 Py]}n (P3) are synthesized in satisfactory yields by Rh-catalyzed polymerization (for P1 and P2) and polymer reaction (for P3). All the polymers are soluble and possess high molecular weights (Mw up to 2.8 3 105). Their structures and properties are characterized and evaluated by IR, NMR, UV, TGA, PL, and photovoltaic (PV) analyses. The polymers are thermally stable, losing little of their weights when heated to 330 8C. When their solutions are irradiated, their perylene pendants emit intense red fluorescence at 610 nm. PV cells with a configuration of ITO/PEDOT:PSS/polymer/LiF/Al are fabricated, which show maximum current density of 10.3 lA/cm2. The external quantum efficiency is sensitive to the polymer structure, with P3 exhibiting the highest value of 0.23%. VVC 2008 iley Periodicals, Inc.

Two novel cyanine dyads, in which a naphthalimide unit is attached to benzoindole ring of unsymmetric trimethine cyanine, have been synthesized via 'Click' reaction and characterized by 1H NMR, 13C NMR, and MS-ESI. Under the illumination of AM 1.5 (75 mW cm 2), the power conversion efficiency of cyanine I reached 4.8% (Jsc=14.5mA cm 2, Voc=0.50, FF=0.49). The results show that the two cyanine dyes are promising sensitizers for nanocrystalline dye-sensitized solar cell.

New poly(1-phenyl-1-alkyne)s bearing acrylic pendants (-(C6H5)CaC[(CH2)mOCOCHaCH2]}n-; P1(m), mZ3, 9) with high molecular weights are synthesized in high yields by WCl6–Ph4Sn catalyst. The structures and properties of P1(m) are characterized and evaluated by IR, NMR, TGA, UV, and PL analyses. All the polymers are solution-processable and thermally stable (TdR380 8C). Upon photoexcitation, the polymers emit strong blue lights with emission efficiencies (O40%) comparable to that of poly(1-phenyl-1-octyne), an emissive disubstituted polyacetylene. No excimeric absorption and emission are observed in the thin films of the polymers. The acrylic moieties of P1(m) are readily cross-linked by UV irradiation without harming their optical properties, which may enable them to find igh-tech applications in photoresist, luminescent patterning, and light-emitting diodes.

Poly(1-pentyne)s containing biphenyl and phthalimido pendant groups with different spacer lengths {P1(m); [HC¼C(CH2)3O Biph OCO(CH2)mN(CO)2C6H4]n, Biph¼4,40 biphenylyl; m ¼ 7, 10} are synthesized in satisfactory yields by WCl6-Ph4Sn catalyst in toluene at elevated temperatures. The structures and properties of the polymers are characterized and evaluated by IR, NMR, TGA, DSC, POM, and XRD analyses. Both of the polymers are thermally stable (Td 300 8C) and exhibit nematicity at high temperatures. Their phthalimido groups are converted into amino groups by hydrolysis, which can, after acidification, complex with lead(II) bromide to furnish polyacetylene-perovskite hybrids in high yields. The organic components contribute good solubility to the hybrids, while the perovskite framework induces the olyacetylene chains to align within the inorganic sheets. The hybrids emit a strong UV light of 374 nm upon photoexcitation, whose quantum yield increases with an increase in the spacer length. VVC 2006 Wiley Periodicals, Inc.
