Abstract

("Figure Presented") Swollen up: Poly(diphenylacetylene) derivatives with different alkyl groups show intramolecular excimer emission that arises from the phenyl-phenyl stack structure in the side chains. The excimer emission is intrinsically correlated with lamellar layer distance. Film-swelling experiments verify that the excimer emission can be modulated by changing the lamella layer distance (see picture).
