Abstract

Organic cocrystals based on noncovalent intermolecular interactions (week interactions) have aroused enormous interest due to their unpredicted and versatile chemicophysical properties and charming applications (Figure 1). In this presentation, I will highlight recent emerging researches of organic cocrystals on reducing aggregation-caused quenching (ACQ) effect, tuning light emission, ferroelectricity, self-healing behavior, switching transport characteristic, and the formation of co-crystals through chemical reaction of organic particles in water. We also summarize great progresses made in this field including revealing the structure-property relationships and developing unusual exciting properties.
