ABSTRACT:
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.
