Abstract
Aspects describe phthalocyanine (Pc) molecules with peripheral modifications of its core (e.g., alkyl substituents) so that the Pc can self assemble, for example under vacuum sublimation, and form nanocrystals of a size on the order of nanometers. The Pc nanocrystals can be prepared, for example, by a simple vapor deposition method. Further aspects describe a polymer composite ink based Pc nanocrystals in a polymer matrix, which can be formed, for example, under a solution process approach. For example, the polymer matrix can be a different p-type conjugated polymer from the Pc nanocrystals, which are inherently p-type semiconductors. This can increase the film formation ability and charge transport properties of the polymer composite ink. The polymer composite ink can be utilized, for example, in the fabrication of optoelectronic devices, such as photovoltaic devices and/or thin film transistors. The optoelectronic devices can exhibit high power conversion efficiency (PCE), for example 6-7 percent.
