Abstract

En 中文

• A series of thermally stable phenazine-based cationic radicals are obtained. • Through stepwise diminishing the steric hindrance of cationic radicals/counteranions, the tighter radical-based π-aggregates are formed. • With the rational regulation of aggregation and introduction of radicals, the absorption cutoff edge is extended to 1500 nm, while the cationic radical possessing a molecular weight of merely 210.1 g/mol. • Remarkable photothermal characteristics and approximately 100% antibacterial efficiency against Staphylococcus aureus are realized.
