An amine-substituted macrocycle , a rigid hexagonal ring, self-assembled into network architecture on the surface, which could be used as a molecular template to directly fabricate gold nanoparticles (AuNPs) with narrow size distribution (2.2 ± 0.1 nm). This work demonstrated a new pathway for the formation of controllable AuNPs on the surface.

Developing luminescent probes with long lifetime and high emission efficiency is essential for time-resolved imaging.H owever,t he practical applications usually suffer from emission quenching of traditional luminogens in aggregated states,o rf rom weak emission of aggregation-induced emission type luminogens in monomeric states.H erein, we overcome this dilemma by ar igid-and-flexible alternation design in donor-acceptor-donor skeletons,t oa chieve at hermally 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 %). Suchadual-phase strong and long-lived emission allows at ime-resolved luminescence imaging,w ith an efficiency independent of probe pretreatment and probe concentration. The findings open opportunities for developing luminescent probes with ausage in larger temporal and spatial scales.
