In this study, we demonstrated that by linking tetrazine to various AIEgens, the weakly-emissive tetrazine-AIEgen complex further suppresses their emission upon aggregation. Following an iEDDA reaction, the resulting emissive pyridazine compounds enhance their emission upon aggregation, affording ultrahigh IAC/IBC. Further investigation concludes that this effect arises from the synergistic interplay between the intermolecular quenching effect of the tetrazine moiety and the AIE property of the fluorogens. We also showcased that this ultra-fluorogenic system can be applied for site-selective fluorogenic imaging of multiple organelles in living cells, highlighting its potential for advanced imaging applications in biological systems. Drawing inspiration from the sociological term "Matthew Effect" 53 -describing the phenomenon that the rich become richer, and the poor become poorer -we coined this unique fluorogenisity as the "Matthew Effect in Aggregate Emission", highlighting intensified darkness of quenched species and amplified brightness of emissive species in aggregate states. This "Matthew Effect in Aggregate Emission" potentially offers a universal strategy for achieving ultrahigh IAC/IBC in fluorogenic nanoaggregate systems.
