Abstract

Excimer (excited state dimer) formation mechanisms in solution have been investigated for a series of acenaphthyl-containing compounds comprising dimers, higher oligomers, and a poly(acenaphthylene) (PAcN) homopolymer. Excimer fluorescence is observed only for dimers with a threo-diisotactic arrangement of the acenaphthyl groups indicating that interactions between nearest-neighbour chromophores are able to play a role in excimer formation in PAcN. An increase in excimer emission is observed with increasing chain length and attributed to additional excimer formation and energy migration processes.
