Abstract
Influence of molecular composition in hemicyanine Langmuir-Blodgett (LB) films, on the aggregation features was investigated by using steady state and time-resolved photoluminescence spectroscopy. It was found that a lower degree of H-aggregation (smaller aggregate size) could be realized in hemicyanine LB films with larger donor groups, leading to a smaller photoluminescence peak blue shift with respect to their solution spectra and longer aggregate lifetime.
