5－（2－硫甲基－4－甲基－5－嘧啶基）－2，4－戊二炔－1－醇α甲基丙烯酸酯非线性光学材料

Nonlinear Optical Material of 5-(2-Methylathio -4-Methyl-5- Pyrimidiny)-2,4-Pentadiyne-1-ol Methyl Acrilate(PDMA)

聚二乙炔（ＰＤＡ）类化合物在超快全光开关、逻辑门和远距离通讯系统的多路传输等方面有着潜在的应用前景。但并不是所有的ＰＤＡ都能用于这些方面，它的选择应当考虑聚合性能、链密度、共轭度、溶解性、热稳定性及可加工性等多方面的因素。本文首次报道了５－（２－硫甲基－４－甲基－５－嘧啶基）－２，４－戊二炔－１－醇甲基丙烯酸酯（ＰＤＭＡ）的合成，该物质极易聚合、链密度高、聚合物可溶、单体热稳定性好，在许多方面可与当前最好的化合物ＰＴＳ及ｐｏｌｙ－４ＢＣＭＵ相媲美。

Polydiacetylenes(PDAs)have important application in superfast all- optical devices,but not all ofthem do,We should consider it's stability,chain-density,solubility and so on. In this paper the synthesisof a novel compound5-(2- methyIthio-4-methy-5-pyrimidinyl)-2,4-pentadiyne-1-ol methyl acrilate(PDMA)has been reported.This compound has good heat -stability,excellent UV- polymerizability andhigh chain-density。It's polymer is soluble in CHCl3.In many aspects,it is comparable with PTS and poly-4BCMU。
