Abstract

Photophysical properties of poly (3-hexylthiophenes) (P3HT) possessing various degrees of regioregularity have been investigated. Wavelengths of emission are blue-shifted for polymers possessing twisted head-to-head (HH) dyads. Quantum yields of luminescence from polymer solutions decreases with increasing head-to-head dyad content of the polymer whereas the reverse is true in thin solid films. The latter can be explained by classical concentration quenching effects which arise from non-emissive excimer complexes. This constitutes an intermolecular decay of excitation.
