Donor–acceptor type aggregation-induced emission luminophores based on the 1,1-dicyanomethylene-3-indanone unit for bridge-dependent reversible mechanochromism and light-up biosensing of hypochlorites

Among three AIE-active molecules with different D–A linkages, TPEIC exhibits reversible high-contrast mechanochromism, light-up sensing and biosensing of ClO⁻.
