Molecular engineering of fluorophore scaffolds, especially heteroatom replacement, is a promising method to yield novel fluorophores with tailored properties for various applications. Yet, molecular origins of the distinct fluorescent properties in newly developed SCOTfluors, i. e., varied emission wavelengths, distinct quantum yields, and fluorogenicity, remain elusive. Such understanding, however, is critical for the rational molecular engineering of high‐performance fluorophores. Herein, we employed quantum chemical calculations to understand the structure‐property relationships of nitrobenzoxadiazole ( NBD )‐like SCOTfluors. Our findings are important not only for the rational deployment of SCOTfluors, but also for the effective modifications of other fluorophore scaffolds, for satisfying the increasingly diversified requirements of bioimaging and biosensing applications.
