Efficient NIR-Light Emission from Solid-State Complexes of Boron Difluoride with 2′-Hydroxychalcone Derivatives

A family of two small and easily synthesizable 1,2,3-triazole molecules with intrinsic white-light-emission in the solid state has been reported. The white light is assigned to the supramolecular aggregate emission (SAE) that is unusual for single-component white light phosphors.

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.
