Two kinds of St/DVB copolymer beeds containing (1 - pyrenyl) formyl and(1 -pyrenyl) methyl groups respectively have been synthesized by both functionalization and copolymerization. The fluorescence spectra of the swollen polymers synthesized are similar in shape to those of the corresponding model compounds, whilethe intensity ratio of excimer to monomer shows clear dependence on the contents ofthe pyrene groups. 展开更多

The photophysical properties of a series of sulfonated micromolecule (paratoluenesulfonic acid, HPTS) and macromolecules (linear and crosslinked polystyrene) have been studied by steady-state fluorescence spectra. The results indicate that the ground sulfonated ring associations can form in both the micromolecules and the macromolecules. The fluorescence spectra of the sulfonated crosslinked copolymers appear a red-shift when the copolymers change from hydrogen-type to sodium-type, and some new emission bands appear in the long-wavelength region. These results are explained in terms of synergetic effect of hydrogen bond,π-πinteraction and crosslinking effect. 展开更多

Bacteriorhodopsin (BR) is a photochromic membrane protein isolated from a strain of halobacteria.Embedment of BR into a polymeric matrix enables the application of the photoactive protein as an optical material.In this work,a chemically crosslinked BR/gelatin film was prepared.The cross-linked film was found to be highly stable even under extreme alkaline or detergent circumstance while BR maintained its bioactivity.The treatments of base and detergents also led to dramatic prolongation of the lifetime of M photoproduct,which might be beneficial for potential applications such as information storage.The BR/gelatin film was demonstrated to tentatively record a simple pattern. 展开更多
