Abstract

We demonstrate a new strategy for designing reversibility, fatigue resistance and fluorescence switching materials, which are based on pyrazolone derivatives by introducing a pyridine ring. The reversible “on” and “off” modulation of fluorescence emission was up to 95% in the solid state.
