Stimulated emission depletion (STED) nanoscopy has broadened our horizons to unravel mysterious functions of cellular structures on an unparalleled nanometer scale. Nevertheless, intense laser power is a general prerequisite for STED super-resolution imaging with satisfactory resolution, inevitably leading severe photobleaching fluorophores, irreparable photodamage biosamples, and impaired quality. Herein, by modulating distinct acceptor units, series donor–acceptor–acceptor structured fluorescent acrylonitriles featured aggregation-induced (AIE) at low were systematically developed. These AIE luminogens (AIEgens) exhibited tunable near-infrared emissions (650–733 nm) high fluorescence quantum yields (QYs up 26.8%) in the solid state, significant Stokes shifts, large two-photon absorption cross-sections. They also typical solvatochromic effect ultrahigh QYs 98.4% low-polarity solvents. Furthermore, these lipophilic specifically lit lipid droplets (LDs) exceptionally photostability wash-free manner.

Aggregate is one of the most extensive existing modes matters in world. Besides research objectives inanimate systems physical science, entities life science can be regarded as living aggregates, which are far from being thoroughly understood despite great advances molecular biology. Molecular biology follows philosophy reductionism, generally reduces whole into parts to study. Although reductionism benefits understanding behaviors, it encounters limitations when extending aggregate level. Holism another epistemology comparable studies at level, emphasizing interactions and synergetic/antagonistic effects a group composed single determining characteristics whole. As representative holism, aggregation-induced emission (AIE) materials have made achievements past two decades both science. In particular, unique properties AIE endow them with situ real-time visual methods investigate inconsistency between microscopic molecules macroscopic substances, offering researchers excellent toolkits study aggregates.
