文摘
- •
Difluoroboron β-diketonate complexes functionalized with carbazole were synthesized.
- •
The highest solid fluorescence quantum yields of difluoroboron complex reached 0.99.
- •
Reversible mechanofluorochromic behaviors were realized upon grinding and fuming.
- •
Ground powder of the complex with tert-butyl carbazole showed thermofluorochromism.
