Abstract
-diphenylaniline) are successfully obtained, and 10 new fluorogenic compounds have been discovered to exhibit seldom-observed tricolored mechanofluorochromic phenomena. Impressively, among them, 8 luminogens demonstrate exceptionally scarce anisotropic force-triggered high-contrast three-color fluorescence responses, which is a commendable achievement, fully verifying the effectiveness of our molecular engineering strategy presented in this study. Furthermore, based on two newly developed representational mechanically responsive tricolor fluorescence switches, three advanced information anticounterfeiting systems are skillfully constructed.
