Fluorescence energy transfer from poly(9,9-dioctylfluorene) to polymeric energy acceptors that include head-to-tail regioregular poly(3-hexylthiophene or P3HT) and poly(2-methoxy-5(2 -ethylhexyloxy)-1,4-phenylenevinylene) or MEH-PPV and monomeric acceptor meso-tetraphenylporphyrin or TPP was studied and correlated with the underlying morphology when the donor-acceptor blends were prepared as drop-coated films or breath-figure structures. It was found that the phase-separate morphology in films and breath figures was influenced by a number of factors, including material transport dynamics, solubility of the blend components in a solvent, interaction of the solvent with the substrate, and the diffusion rate of the blend components.
