The suppression of the collective excitations in a novel form of quinquithienyl prevents charge photoproduction and evidences the spectroscopical properties of the isolated molecules in their planar form. The strong reduction of the photoluminescence quantum yield and the non-exponential decay of the photoluminescence in the aggregated molecules are accounted for in terms of exciton dynamics.

Abstract
The suppression of the collective excitations in a novel form of quinquithienyl prevents charge photoproduction and evidences the spectroscopical properties of the isolated molecules in their planar form. The strong reduction of the photoluminescence quantum yield and the non-exponential decay of the photoluminescence in the aggregated molecules are accounted for in terms of exciton dynamics.File in questo prodotto:
