title: Fluorescence quenching of substituted polyperylene with functionalized polythiophenes.
abstract: The present investigation focuses the influence of polythiophene i) containing hetero aromatic structures and ii) containing mesogenic groups towards the photoluminescence properties of substituted polyperylene (PPE). The structural contribution towards the optical properties was individually discussed. The photoluminescence of PPE was quenched to the maximum level (30%) when it was blended with polythiophene with mesogenic groups containing longer alkyl spacer. Results of the same blend in solid-state shows 85% of PL quenching.
