Abstract

It was found that, in diacetylene oligomers constisred of monomer units with an non-conjugated system of π-electrons, the efficiency of fluorescence quenching depends on the chain length within the range from 2 to 40 repeating units. This effect is consistent with the model of propagation of delocalized excitons in a noncovalent aggregate of several oligomer chains. The result obtained in the study confirms the assumption that a collective effect due to excitons can exist in a supramolecular aggregate of non-conjugated molecules. © Pleiades Publishing, Ltd., 2013.
