摘要

Abstract >Developing luminescent probes with long lifetime and high emission efficiency is essential for time‐resolved imaging. However, the practical applications usually suffer from emission quenching of traditional luminogens in aggregated states, or from weak emission of aggregation‐induced emission type luminogens in monomeric states. Herein, we overcome this dilemma by a rigid‐and‐flexible alternation design in donor–acceptor–donor skeletons, to achieve a thermally activated delayed fluorescence luminogen with high emission efficiency both in the monomeric state (quantum yield up to 35.3?%) and in the aggregated state (quantum yield up to 30.8?%). Such a dual‐phase strong and long‐lived emission allows a time‐resolved luminescence imaging, with an efficiency independent of probe pretreatment and probe concentration. The findings open opportunities for developing luminescent probes with a usage in larger temporal and spatial scales. </abstract> </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display:
