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 con®rmed, in selected temperature ranges, by FTRaman 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

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 con®rmed, in selected temperature ranges, by FTRaman 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
