Aimed Synthesis of Organic Alloys and Heterostructures via Precision-Tailored Routes
The primary objective of this study is to thoroughly explore the processes of homogeneous nucleation in alloys and heterogeneous nucleation in organic heterostructures, with the ultimate goal of gaining precise control over the selection between two nucleation mechanisms. By using Perylene (Pe) as the donor and isomers of tetrachlorophthalonitrile as the acceptors, alloys with continuously tunable luminescent colors were successfully synthesized in a one-step process. Additionally, using two-step synthesis, microcrystals of triblock and semi-core/shell heterostructures, composed of cocrystals and alloys, were successfully prepared. Notably, the formation of the two types of heterostructures was elucidated, emphasizing the kinetic and thermodynamic effects on the nucleation of cocrystals. Additionally, the heterostructures facilitate the construction of optical logic gates with photonic coding.
