| Outline of Final Research Achievements |
Highly emissive and stable multicolor sulfonylaniline-based fluorescent dyes have been prepared through different combinations of substituents. These fluorescent dyes showed emission in both solution and solid states, where intra- and intermolecular hydrogen bonds dominate, respectively. Moreover, the orbital energy and optical properties were fine-tuned, revealing that there was good correlation between the orbital energy and the electron-donating ability of the substituent. These molecules present a new trend for the design of organic fluorescent small molecules, and in particular, include a rational concept: fine tuning of optical properties via molecular-orbital distribution control. These findings are useful for orbital energy control in organic optoelectronic materials.
