Exploring organic reactions to construct novel molecules with aggregation-induced emission (AIE) features is an essential branch of AIE research. The fast-paced application materials in various disciplines, including photoelectricity, molecular biology, medicine, and science, has led ever-growing need for new molecules. Unlike the synthesis most "earlier generations" fluorogens (AIEgens) that require tedious harsh reactions, chemists now shift their synthetic focus a selection reliable straightforward reactions. Diels-Alder reaction been overlooked this field. Herein, we report catalyst-free between 1,3-diphenylisobenzofuran series electron-deficient alkynes create AIEgens. Photophysical properties our synthesized 1,3,4-triphenyl-1,4-dihydro-1,4-epoxynaphthalene (ENAP) derivatives are studied systematically, manifesting characteristics structure-fluorescence property relationships. Finally, highlight diverse applications some selected ENAP latent fingerprint detection, cell imaging, bacterial staining.
