Nonlinear optical (NLO) properties of the clusters (Me.N)2[Cu4(SPh)6] (I) and (Me4N)2[Ag6(SPh)a] (II) were studied with a 7 ns pulsed liner at 532 nm. Both I and II exhibit NLO absorption and NLO refraction, which can be roughly described by third-order processes. A wide transparent window (λ=400-1000nm) was observed for both clusters, which leads to reintively large values of the figure of merit, W (=n2//(aoλ)|). The W value is 32 and 5 for I and If, respectively, at incident irredinnce of 0.3 GW cm-2. The nonlinear optical properties of the clusters were related to the extent of electron delocnlization of their HOMOs and LUMOs. Structurnl factors that may lead to optimization of linear and nonlinear optical of a material were discussed.

The monolayer properties of p-tert-butylthiacalix[4]arene (TCA) at the air-water interface was investigated by the measurements of surface pressure-area isotherms. However, TCA only exists as a trimmer aggregate on the subphase of deionized water. Copper (II) ion in the subphase can induce the monolayer formation of TCA. The UV-Vis spectra and FTIR spectra of the transferred films suggested that the monolayer formation was fulfilled through the coordination of copper (II) ion to TCA at the air-water surface.

通过萃取的方法，详细研究了硫杂杯[4]芳烃在不同pH、不同的摩尔配比的萃取剂及不同浓度铅离子等不同条件下的萃取作用，确定了萃取的最佳条件。为硫杂杯[4]芳烃应用于富集或排除铅离子提供了理论依据。

Three new thiacalix [4] arene derivatives, 5,11,17,23-tetra-tert-butyl-25,27-di (2-hydroxyethoxy)-26,28-dihydroxythiacalix-[4] arene (2), 5,11,17,23-tetra-tert-25, 26,27,28-tetrakis [(methylcarboxyl)methoxy] thiacalix [4] arene (3), 5,11,17,23-tetratert-butyl-25,26,27,28-tetrakis(2-hydroxy-1-propanoxy)thiacalix [4] arene (4), were synthesized for the first time. The coordination properties of thiacalix [4] arene (1) and its derivatives (2and4) were investigated by detecting the interactions between these compounds and two palladium complexes, cis-[Pd(en)(H2O)2]2+ and cis-[Pd(dtco-3-OH)(H2O)2]2+, by means of electrospray ionization mass spectrometry (ESI-MS) technique.

Several new nitrogen-containing calixarene derivatives have been synthesized and their ion-binding properties investigated by UV spectroscopy and solvent extraction. These derivatives include 5,11,17,23-tetra-t-butyl-25,26,27,28-tetrakis (piperidinocarbonylmethoxy) calix [4] arene (5), 5,11,17,23,29,35,41,47-octa-t-butyl-49,50,51,52,53,54,55,56-octa (piperidinocarbonylmethoxy) calix[8]arene (6) and 5,11,17,23,29,35,41,47-octa-t-butyl-49,50,51,52,53,54,55,56-octa(N,N-diethylcarbamoylmethoxy) calix[8]arene (7). The UV spectra of 6 and 7 revealed they had an ability to transform tight lead picrate ion pairs into separated ones by complexation with Pb2+ in tetrahydrofuran. Both derivatives give 1: 1 complexes with Pb2+. Extraction studies showed that these derivatives could efficiently extract Pb2+ (as picrate salts) from the aqueous phase into chloroform. The extractability of these derivatives were also compared with that of the oxygen-containing ester derivative calix [8] arene 2 and the other two nitrogen-containing compounds 8 and 9.
