摘　　要：Exploring the factors to control Znsalen aggregation is of importance to design functional materials in catalysis, optical materials and biological imaging. In this work, we synthesized and characterized four cryptand type tri Znsalen complexes and found that cryptand structure could efficiently minimize intermolecular Zn…O interaction. More importantly, encapsulated by PLGA nanoparticles, cryptand tri Znsalen 1 displayed visible intracellular fluorescence whereas monomeric Znsalen 5 could not. These results provide a new access to design new luminescent materials with the potential application in optics and biological studies.Exploring the factors to control Znsalen aggregation is of importance to design functional materials in catalysis, optical materials and biological imaging.
