Summary: We discovered a general design principle for materials that exhibit multiple room-temperature phosphorescence (RTP) processes. By modulating the hybridization between donor and acceptor groups, we achieved multiple RTP processes in sp3 C-linked donor-acceptor compounds. However, in sp2 C-linked counterparts, only one locally excited triplet state phosphorescence was observed due to enhanced excitonic coupling. Our findings provide insights into the dynamics of higher-lying triplet excited states and offer a fundamental design principle for compounds with multiple RTP.

Summary: For organic opto-electronic materials, the macroscopic performance of molecular aggregates is not simply the combination of single molecules. The review focuses on the regulation of molecular aggregation to improve and generate luminescent properties. Mechanoluminescence (ML) and room-temperature phosphorescence (RTP) are emphasized as emission properties sensitive to molecular aggregates. The study also highlights the dynamic photophysical properties related to molecular motions and/or packing modes, as well as the adjustable molecular packing in different functional materials.

Summary: Long-lived organic room-temperature phosphorescence materials have great potential applications in various fields. Compared to traditional fluorescence, phosphorescence originates from slow radiative transitions of triplet excitons. Enhancing intersystem crossing rate and suppressing nonradiative relaxation channels can achieve efficient phosphorescence in purely organic materials. Amorphous organic polymers offer improved processability and flexibility, making them more competitive for achieving long-lived phosphorescence emission.

Summary: In this study, a catalyst-free thiol-yne click reaction was used to develop sulfur atom-based photosensitizers (PSs) with enhanced intersystem crossing (ISC) effects. The introduction of a tetraphenylpyrazine-based aggregation-induced emission (AIE) unit was advantageous for promoting ISC in the aggregated state. Furthermore, the sulfur atom electron donor, double-bond pi bridge, and AIE electron acceptor created a donor-pi-acceptor (D-pi-A) molecular system with excellent two-photon excitation properties. The resulting polymer nanoparticles exhibited exceptional in vitro two-photon-excited PDT towards cancer cells, showing great potential for deep-tissue disease therapy.
