Dependences of the photoluminescence of conjugated polymer poly (p-phenylene) (PPP) thin films on different lengths of polymer chain and temperatures of the samples have been studied using steady-state fluorescence spectroscopy and the time-correlated single-photon counting technique.
Charge carrier photogeneration in solid porphyrin films was investigated using optical and photocurrent action spectroscopy. In electropolymerized DA porphyrin films on ITO, acting as photo diodes, unidirectional charge separation occurs within interfacial heterodimers if E D,A (S 1 )-E CT in solution is sufficiently large. In covalent porphyrin dimers on TiO...
