报告内容:
Long-lived room temperature phosphorescence materials have attracted increasing attention because of their fantastic properties and application potentials. Inspired by the importance of noncovalent interactions such as hydrogen bonding andp-pstacking interactions in supramolecular self-assembly as well as covalent polymerizations, we have prepared functional amorphous systems by integrating suitable chromophore molecules and polymer matrix in order to achieve long-lived room temperature phosphorescence. Through rationally integrating selected chromophores with polymers noncovalently and covalently, the formations of unique interactions and bonding in the resulted systems could effectively minimize the molecular vibrations and promote the intersystem crossing for enhanced room temperature phosphorescence. These systems show promising applications in displays, imaging, data encryption and information storage. In this talk, I will present our recent research progress about the design, synthesis, mechanism study and applications of polymer-enhanced room temperature phosphorescence systems.
