Abstract :
We report the temperature dependence of the dielectric properties of poly[1,6-bis(3,6-didodecyl-N-carbazolyl)-2,4-hexadiyne] (polyDCHD-S) from 30 to 400 K. The data obtained from these measurements are confirmed, in selected temperature ranges, by FT-Raman spectroscopy, differential scanning calorimetry and X-ray diffraction. The transition from the blue to the red form in polyDCHD-S is detected in correspondence to the monomer melting point (about 340 K). Other transitions, above and below this feature, are reported and discussed.
