ABSTRACT
A fluorophore consisting of two fluorescent moieties could display unusual optical behaviors that are unattainable in a single-fluorophore compound. Herein we reported two “dual-fluorophore” dyes: DNS-linked tetraphenylethene demonstrates bright aggregation-induced emission, while NBD-linked tetraphenylethene exhibits aggregation-caused quenching. Our results have important implications for engineering emission behaviors of molecular aggregates for practical applications.
