    • 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.
    • 提供了新的咔唑基二炔单体和聚合物。 单体具有结构,其中“m”和“n”为0至10的整数,X和Y独立地选自-H,-Cl,-Br和-NO,R为 选自-CH 3,-OH,-OCONHR'和的成员,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。 通过溴代乙炔与末端炔类的交联,或通过碱性咔唑与适当的二乙炔的取代反应,可以方便地制备端基咔唑乙炔的氧化偶合。 聚合物通过固体状态的相应单体的1,4-加成反应制备。 聚合物特别用作光电导体和非线性光学材料。 单体可用作高能辐射剂量指示剂。
