"overcomes irreversible signal loss/ limited triggers/ natural non-emissivity under ambient conditions due to concentration-caused quenching... pressure induces phase transition (monoclinic-to-triclinic)/ N,N-dimethylformamide exposure triggers bright yellow emission with 97% photoluminescence quantum yield... gentle heating removes solvent, reversing... 0D hybrid framework allows for significant structural distortion without compromising integrity >10+ cycles... anti-counterfeiting, optical computing, sensors"
