项目摘要

This study aims at synthesizing functionalized polydiacetylenes. It is divided into two parts; the one is the preparation of thin solid films of amphiphilic diacetylenes and the other is the synthesis of crystalline ionomers of diacetylenes.1. An Attempt to Prepare a Thin Solid Film of Mixed DiacetylenesThe materials used were 10,12-heptacosadiynoic acid ans 1,2i-dicarbazoly1-10,12-docosadivn-1,22-dione. Monolayer of this mixed monomers (10:1) was spread onto aqueous subphase. Multilayer, prepared by the Langmuir-Blodgett technique on a glass plate, was irradiated with UV. The multilayer turned blue within 10 min.2. Synthesis of Crystalline Ionomers of DiacetylenesCalcium, cobalt, nickel, copper, zinc, cadmium, and barium 10,12-docosa-diynoates were prepared. Irradiation with UV gave colored polymers. The zinc salt gave the best results in terms of reactivity. The zinc polymer showed X-ray reflections. This fact indicates that the polymer is two-demensional crystalline polymer cross-linked with zinc.More work is needed in order to characterize the polymers and to improve the processability of the cross-linked crystalline polymers.

本研究旨在合成功能化聚二乙炔。本论文分为两部分，一部分是两亲性二乙炔固体薄膜的制备，另一部分是二乙炔离聚物的合成.以10，1,2-二十七碳二炔酸和1，2 i-二咔唑基-10，1,2-二十二碳二炔-1，22-二酮为原料制备混合二乙炔固体薄膜。将该混合单体（10：1）的单层铺展到含水亚相上。多层膜，通过LB技术制备的玻璃板上，用紫外光照射。多层膜在10分钟内变蓝。合成了10，12-二十二碳二炔酸钙、钴、镍、铜、锌、镉和钡的结晶离聚物。用UV照射得到有色聚合物。锌盐在反应性方面给出最好的结果。锌聚合物显示X射线反射。这表明该聚合物是一种与锌交联的二维结晶聚合物，但仍需进一步研究以表征聚合物的结构和改善交联结晶聚合物的加工性能。
