Novel photoactive polymeric multilayer films formed via electrostatic self-assembly
We demonstrate a novel approach for constructing photoactive multilayer films in which the aggregation of fluorescing molecules is effectively eliminated. In the films formed via a layer-by-layer electrostatic self-assembly technique, the core-shell amphiphilic copolymer, poly[(sodium 4-styrenesulfonate)-block-vinylnaphthalene], was deposited. The isolated cores served as nanosized host sites for photoactive guest molecules (pyrene, perylene). The efficient energy transfer between polymeric chromophores and perylene molecules was observed.
