The effect of N-methylation on photophysical properties of imidazole-based fluorescent molecules

Our research revealed that the introduction of a methyl group had a profound effect on the molecular geometry, resulting in a more twisted structure. As a consequence of this non-planar structure, the material exhibited aggregation-induced emission properties, making it a promising candidate for various practical applications. To support our findings, we used a range of analytical techniques, including UV-vis absorption spectra, fluorescence spectra, and theoretical calculations. This work provides valuable insights into the relationship between molecular structure and optical properties, which could inform the development of novel materials for a range of applications.
