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 tetraamino derivative of thiacalix [4] arene (4) was synthesized and characterized. Its acid-base property in water solution was studied by UV spectroscopy. The pH distribution regions of several acidic or basic species of 4 were determined.

To prepare calixarene-based polymers with proton transport ability, the calix [4] arene derivatives with one polymerizable group at the upper rim were first prepared via selective nitration, amination, and acrylamidation of calix [4] arene. Two methods, solution polymerization and emulsion olymerization, were then employed to carry out the copolymerization of these derivatives with other monomers such as styrene, vinyl acetate, or methyl methacrylate. Transport experiments show that the resulting calixarene-based polymers have a very good ability to transport protons.

Several new calixcrowns were synthesized and characterized. The transport of Ca2 + ion was investigated through a bubbling pseudo-emulsion liquid membrane with these calixcrowns, the parent calix [n] arenes (n=4, 6, 8) and the ester, acid derivatives of calix [4] arene as mobile carriers. The effects of the initial concentrations of Ca2 + ion in the source phase and the initial pH difference (ΔpH) between the receiving phase and the source phase were studied. The results suggest that there are two different transport mechanisms. The transports using calixarenes and their ester, acid derivatives as carriers represent a proton-coupled co-transport with a flow of protons in the opposite direction, while the transports using the calix-crowns as carriers exhibit the characteristics of an anion-cou-pled co-transport with a flow of anion in the same direction.
