Abstract
- In this article, a BF2-containg dye was configured and routinely characterized by 1H NMR and MS technology. This BF-cored dye shows intensive emission in chloro-carbon solvents, for example dichloromethane, with the emission peak 475 and 515 nm. The emission profiles almost the mirror image of the absorption of profile. The highly emissive character may ascribe to the coordinate lock, which limited the free rotation of benzene ring and nonradiation transition. Therefore, the dye exhibits highly emissive character. Even if the molecular framework is small, a larger Stoke's shift (170 nm) was observed. Additionally, the emission in film shifts 5 nm more than that in solution. In solid state, the emission maximum reached to 525 nm. In all the case, the emission colors were demonstrated by International Commission on Illumination (CIE) chromaticity system.
