Stimuli Response

Novel maleic anhydrides symmetrically substituted by two aromatic rings exhibit distinct emission behaviours: aggregation-caused quenching (ACQ), aggregation-induced emission (AIE), and dual-state emission (DSE) in both solution and the solid state. Appropriate modifications were made to turn ACQ/AIE into DSE and realize full-color DSE.

Reliable Methods

In order to develop reliable methods for the synthesis of various 5-substituted-8-oxyquinoline derivatives for the preparation of Alq3-type complexes, we have improved the reaction conditions on some syntheses described in the literature, successfully synthesized new ligands based on quinolin-8-ol and characterized their chemical structures by NMR. Some of the synthesized quinolin-8-ol derivatives containing incorporated bulky triphenyl or tert-butyl groups showed blue luminescence in the solid state due to the possible aggregation induced emission enhancement (AIEE) with a maximum wavelength around 510 nm. More detailed light-emission property investigation of the mentioned bulky group containing compounds is currently underway.
