Novel carbazolyl diacetylenic monomers and polymers are provided. The monomers have the structure ##STR1## where "m" and "n" are integers of from 0 to 10, X and Y are independently selected from the group consisting of --H, --Cl, --Br and --NO and R is a member selected from the group consisting of --CH.sub.3, --OH, --OCONHR' and ##STR2## where R' is an alkyl, aryl or ester derivative and X' and Y' are independently selected from the group consisting of --H, --Cl, --Br and --NO. The monomers are conveniently prepared by oxidative coupling of terminated carbazolyl acetylenes, by cross coupling of bromoacetylenes with terminal acetylenes, or by substitution reaction of alkali carbazolides with the appropriate diacetylenes. The polymers are prepared by 1,4-addition reaction of the corresponding monomers in the solid state. The polymers are particularly useful as photoconductors and as non-linear optical materials. The monomers are useful as high energy radiation dosage indicators.
本发明提供了新型的咔唑基二乙炔单体和聚合物。该单体具有以下结构式##STR1## 其中“m”和“n”是0至10之间的整数,X和Y独立地选自--H、--Cl、--Br和--NO组成的基团,R是选自--CH.sub.3、--OH、--OCONHR'和##STR2## 其中R'是烷基、芳基或酯衍生物,X'和Y'独立地选自--H、--Cl、--Br和--NO组成的基团。该单体可通过终止的咔唑基乙炔的氧化偶联,溴乙炔与末端乙炔的交叉偶联,或碱性咔唑化合物与适当的二乙炔的取代反应方便地制备。聚合物通过在固态下进行相应单体的1,4-加成反应制备。该聚合物特别适用于光导体和非线性光学材料。该单体适用于高能辐射剂量指示器。
