Light-Induced Conductivity in a Solution-Processed Film of Polydiacetylene and Perylene Diimide

We prepared a solution-processed film comprising a drop-carted mixture of melamine-diacetylene and perylene bis(dicarboximide) (PDI). We show that the diacetylene monomers adopt distinct crystalline organization in the presence of the PDI residues. Importantly, the drop-tasted diacetylene/PDI film exhibits ultraviolet light induced conductivity, ascribed to effective transport of charge carriers in the conjugated polymerized network.
