Abstract
- A series of novel coronene-based fluorescent materials have been synthesized through well-defined protocol from 1,2-dimethoxybenzene, with the key steps including Suzuki–Miyaura coupling and oxidative cyclodehydrogenation with ferric chloride. Fluorescence spectra investigations proved that they have emissions in the range λ 460-470 nm with excitation wavelength at λ 373 nm. It is found that different chromophores from substituents can significantly enhance the fluorescence intensities, which paves a new way of application of these materials in various fields.
