Preparation and roperties of thin solid films of polydiacetylenes

本研究旨在合成功能化聚二乙炔。它分为两部分；一是两亲性丁二炔固体薄膜的制备，二是丁二炔结晶离聚物的合成。 1．制备混合丁二炔固体薄膜的尝试使用的材料是10,12-二十七二炔酸和1,2i-二咔唑基1-10,12-二十二碳二酮-1,22-二酮。将这种混合单体（10:1）的单层铺展到水性底相上。通过 Langmuir-Blodgett 技术在玻璃板上制备多层膜，并用紫外线照射。多层膜在 10 分钟内变成蓝色。2。二乙炔结晶离聚物的合成制备了10,12-二十二碳二炔酸钙、钴、镍、铜、锌、镉和钡。用紫外线照射得到有色聚合物。就反应性而言，锌盐给出了最好的结果。锌聚合物显示出X射线反射。这一事实表明该聚​​合物是与锌交联的二维结晶聚合物。为了表征该聚合物并改善交联结晶聚合物的加工性能，需要做更多的工作。

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.
