ABSTRACT:
Chemical modification of crystalline poly-1,6-di-(N-carbazolyl)-2,4-hexadiyne is disclosed. There is provided a chlorinated poly-1,6-di-(N-carbazolyl)-2,4-hexadiyne having at least 12 chlorine atoms per repeat unit. The chlorinated poly-1,6-di(N-carbazolyl)-2,4-hexadiyne of the invention is characterized by a Fourier transform infrared (FTIR) spectrum including peaks at about 745.+-.5, 798.+-.5, and 851.+-.5 cm.sup.-1. There is also provided a nitrated poly-1,6-di-(N-carbazolyl)-2,4-hexadiyne having at least 2 nitro groups per repeat unit. The nitrated poly-1,6-di-(N-carbazolyl)-2,4-hexadiyne of the invention is characterized by an FTIR spectrum including absorption at about 1511.+-.5, 1342.+-.5, 794.+-.5, 751.+-.5, and 718.+-.5 cm.sup.-1.
