Achieving high-contrast tricolor emissive regulation of a single-component molecule using single type external stimulus is highly desirable but challenging. In the present study, we report symmetric acceptor-donor-acceptor (A-D-A)–type aggregation-induced emission-active luminogen, which displays sequential fluorescence switching just by anisotropic mechanical grinding. Specifically, upon light grinding, an orange–yellow-to-blue hypsochromic mechanofluorochromic response with distinct color contrast (change in maximum emission wavelength, Δλ em,max = 122 nm) noticed, and slightly ground solid exhibits blue-to-red (Δλ 185 bathochromic conversion vigorous Thus, luminogen developed here, can realize wide-range > 100 hypso- mechanochromisms simultaneously. The tricolored phenomenon attributed to two different morphological transitions involving crystalline-to-crystalline crystalline-to-amorphous states. Furthermore, three information anticounterfeiting systems are presented here.

The design, synthesis, and optimization of excited-state intramolecular proton transfer (ESIPT)-associated dual-emissive aliphatic conductive polymer is one the very challenging tasks, has not been reported to date. Herein, fluorescent conducting polymers (FCPs) are synthesized by polymerizing N-(monomethylol)acrylamide (MMA), acrylic acid (AA), in situ-generated 3-N-(monomethylolacrylamido)propanoic (NMMAPA). Of different FCPs, maximum population heteroatomic nontraditional luminophores, i.e., secondary amide (−CONH), imidol (−CN(OH)), tertiary (−CON), carboxylic (−COOH), FCP4 supported spectroscopic analyses, thermal profiles, fluorescence enhancements, computational calculations. Thus, further investigations made on explore photophysical properties, check suitability dual metal ion sensing, study conductivity.
