A novel compound 2,6-diphenyl-1,5-diaza-1,5-dihydro-s-indacene (Indacene) was synthesized by means of the Madelung reaction starting from 2,5-dimethyl-1,4-phenylenediamine. The structure was characterised by NMR, IR, MS, and elemental analysis. The UV/Vis absorption and photoluminescence spectra were investigated. The electroluminescent behaviour of the new compound was studied in ITO/PEDOT-PSS/Indacene-CNPPP/Mg-Ag(10:1)/Ag devices. The electroluminescent maximum was recorded at 504 nm corresponding to a greenish blue emission. The results demonstrate the potential application of Indacene in OLEDs.

【期刊论文】Photoconductivity Study of Modified Carbon Nanotube/Oxotitanium Phthalocyanine Composites

Carbon nanotubes (CNTs) bonded to dodecylamine groups were obtained by chemical modification. The modified CNTs showed improved solubility in organic solvents and miscibility with polymer matrix. The photoconductivity of oxotitanium phthalocyanine (TiOPc) doped with modified CNTs was investigated by the xerographic photoinduced discharge method. The results showed that the photosensitivity of the duallayer photoreceptor (P/R) with modified CNT/TiOPc composite as charge generation material was higher than that with pristine TiOPc and increased with increasing the content of modified CNTs in the composites. It was explained that, as demonstrated by X-ray photoelectron spectroscopy (XPS), after doping with modified CNTs, the intramolecular charge transfer occurred in TiOPc and the charge-transfer exciton was prone to be produced, which was favorable to charge carrier generation. The efficiency of charge carrier separation increased as well because of the photoinduced charge transfer between TiOPc and CNTs, which might also contribute to the improved photosensitivity of the modified CNT/TiOPc composites.

【期刊论文】Unique Aggregate Structure of Fluoroperylene Diimide Thin Film
陈红征, Min-Min Shi, Hong-Zheng Chen, * Yue-Wen Shi, Jing-Zhi Sun, and Mang Wang*

A perfluorinated perylene diimide, N,N¢-diperfluorophenyl-3,4,9,10-perylenetetracarboxylic diimide (DFPP), and its nonfluorinated analogue, N,N¢-diphenyl-3,4,9,10-perylenetetracarboxylic diimide (DPP), showed similar UV-vis absorption and fluorescence spectra when they existed as monomeric dyes in solutions, whereas in solid films they exhibited great differences. Absorption band splitting was observed for DPP film; however, for DFPP film, the fine structure of absorptions similar to that in solution still remained in addition to the absorption peaks becoming broader and shifting to longer wavelength regions. Furthermore, it was found that DFPP molecules aggregated to form a crystalline film when the temperature of the substrate was elevated to 200℃. Through the simulation of the molecular conformation, the theoretical examinations of molecular interactions, the measurement of electron affinity, the observation of the film morphology by AFM and SEM, and the crystalline structure characterization by XRD, the unique aggregate structure of the crystalline DFPP thin film was suggested: DFPP molecules stacked with the perfluorinated phenyl groups straight over or below the perylene cores of the adjacent DFPP molecules.

【期刊论文】Excellent ambipolar photoconductivity of PVK film doped with fluoroperylene diimide

We report a novel bipolar charge transport material in a single-layer photoreceptor. Using the so-called photoinduced xerographic discharge technique, photoconductivity of the material was measured in positive charging and negative charging conditions, respectively. In both cases, it exhibited excellent photoconductivity. The material was obtained by doping poly(N-vinyl carbazole) (PVK) with a novel organic electron acceptor of N; N0-diperfluorophenyl-3,4,9,10-perylenetetracarboxylic diimide (DFPP). The combined efforts of UV-Vis absorption, DSC, XPS and cyclic voltammetry characterizations demonstrated that D-A complex was formed between DFPP (A) and PVK (D) due to their different electron affinities. The data also suggested that electron transport channels composed of DFPP molecules might exist in the film, providing the film not only high exciton dissociation efficiency but also good electron transport ability. The electronic and structural properties of the DFPP-doped PVK film are also reported.

【期刊论文】Fluoroperylene diimide: a soluble and air-stable electron acceptor

A novel soluble and air-stable electron acceptor was reported: due to the fluorination, N,NA-diperfluorophenyl3,4,9,10-perylenetetracarboxylic diimide (1) possessed not only good solubility but also much lower LUMO energy level: 24.37 eV. Furthermore, the photoinduced charge transfer between 1 and PVK was also studied.

【期刊论文】Structure-Property Relationships for Photoconduction in Substituted Polyacetylenes

New photoconductive materials are explored from three groups of polyacetylenes: poly (phenylacetylenes) [HC-C(C6H5-p-R)]n-, poly(3-thienylacetylenes) -[HC-C(3-C4H2S-3 R)]n-, and poly(1-alkynes)-{HC-C[(CH2)mR"]}n-, where R=CH3 (2), CO2(CH2)6OCO Biph-OC7H15 (Biph=4,4'-biphenylyl; 3); R'=Si(CH3)3 (4), Br (5); and R"=CO2(CH2)6OCO-Biph-OC9H19 (m=2; 6), 9-carbazolyl (m=3; 7) and OCO-Biph-OC7H15 (m=9; 8). Photoconduction in the polyacetylenes under illumination of visible light is investigated using photoinduced xerographic discharge technique. In the pure (undoped) state, all the polyacetylenes except 5 show higher photosensitivity than do poly(phenylacetylene) (R H; 1), a well studied photoconducting polyacetylene, and poly (9 vinylcarbazole), the best known photoconducting vinyl polymer. Among the polyacetylenes, photoconduction perfor mance of the polymers with electron donating and/or hole transporting moieties is superior to those with electron accepting ones. The liquid crystalline polymer 6 exhibits very high photosensitivity, probably due to the formation of crystalline aggregates of its mesogenic pendants induced by the thermal treatment in the photoreceptor preparation process. C60 acts as a photoconductivity enhancer when doped to amorphous 3, but functions as a crystallinity breaking plasticizer when doped to liquid crystalline 6, leading to a large decrease in photoconductivity. While 3 shows a low photosensitivity (2.8
