| 摘 要： | 一般说来,高分子材料可以由小分子单体通过化学键结合而成1],也可以通过非化学键的所谓超分子组装而成2～4].后者是近年来高分子合成中十分活跃的领域.我们尝试将上述两种方法相结合来设计合成高分子功能材料,利用超分子化学法在设计功能性基团方面的便利性2,5]和经典化学法在成键方面的有效性,提出了用"超分子结构单元"构筑高分子的方法.

| Abstract: | A new method to prepare functional polymeric materials was introduced.The materials were manufactured by using supramolecular blocks other than monomers.The supramolecular block,which is an assembly of many same kinds of molecules or different kinds of molecules and particles,can show unique properties different from its original molecule or particle.As an example,a supramolecular luminescent block was prepared by assembly of organic luminescent molecules of (4-methacryloyloxy)trans-stilbenyltrimethylammonium bromide (MSTAB) with semiconductor nanoparticles of CdSe.CdSe nanoparticle is as a core and MSTAB as shell.The block showed a very high increase in photoluminescence intensity of CdSe nanoparticles.A composite material with unique optical properties and good compatibility of two different kinds of phases was obtained by “polymerization" of the blocks. |
