Abstract

The first second-harmonic generation field-induced molecular reorientation experiments in a dye-doped polymer in the 100 K to 500 K temperature range is reported. The (alpha) transition, related to the mobility of the polymer backbone, is easily observed. We also see evidence of the (beta) transition (attributed to side-chain mobility). We demonstrate the low- temperature end of our data suggests that the polymer acts as a rigid elastic constraint to the chromophore. We also observe what appears to be a spontaneously ordered phase of the doped polymer that ma be associated with the polymer/substrate interface. We report on the temperature-dependent phase transition of the transparent indium tin oxide electrode. Suggestions are made on separating the ITO contribution from the polymer response.
