摘要： Thin films of organic semiconducting material comprising perylene diimide small molecules with pyrrolic N—H bonds. Films are prepared using green solvents including water and alcohols. The films can be solvent-resistant and generally range in thickness from 10 to 1000 nm. Perylene diimide molecules are dissolved in solvent by addition of a base to polarize the pyrrolic N—H bond believed to generate an ionic salt in alcohol or aqueous solution. Devices containing such films are provided. Methods of making films and methods of using films in OPV device applications and in amine sensors are provided.
