Organic near infrared (NIR) persistent-luminescence systems with bright and long-lived emission are highly valuable for applications in communication, imaging, sensors. However, realizing these materials (especially lifetime over 0.1 s) is a challenge, mainly because of non-radiative quenching their excitons. Herein, universal strategy stepwise Förster resonance energy transfer (FRET) NIR system remarkable persistent luminescence (up to 0.2 s at 810 nm) presented, based on new...
Abstract Organic type‐I photosensitizers (PSs) which produce aggressive reactive oxygen species (ROS) with less oxygen‐dependent exhibit attractive curative effect for photodynamic therapy (PDT), as they adapt better to hypoxia microenvironment in tumors. However, the reported PSs are limited and its exacted mechanism of dependence is still unclear. Herein, new selenium‐containing Se6 Se5 benzoselenadiazole acceptor has been designed possessed aggregation‐induced emission characteristic....
Developing stable room-temperature phosphorescence (RTP) emission without being affected by moisture and mechanical force remains a great challenge for purely organic systems, due to their triplet states sensitive the infinitesimal motion of phosphors oxygen quencher. We report kind highly robust phosphorescent doping rigid phosphor into copolymer (polyvinyl butyral resin) matrix with balance mutually exclusive features, including rigidly hydrophilic hydrogen bond network elastically...
Perovskite light-emitting diodes (PeLEDs) emerge as a promising class of optoelectronic devices for next-generation displays and lighting technology. However, the performance blue PeLEDs lags far behind that their green red counterparts, including unachieved trade-off between high efficiency luminance, severe roll-off, unsatisfactory power efficiency.

It remains challenging to develop organic afterglow materials with a variable emission color and not single during decay. Herein, we developed kind of time-dependent multicolor polyurethane (PU) system whose can undergo four distinct changes within 1.0 s. The rapid UV-cured copolymerization pyrene-1-carboxylate derivative (PyC) poly(ε-caprolactone) (PCL) prepolymer ensured that the resulting PU systems possessed dual persistent luminescence phosphorescence at 626 nm lifetime over 200 ms...
A kind of NIR afterglow with a lifetime 0.16 s at 808 nm was prepared using triplet excimer (PVB@PVA) as the donor. PYB 2 @PVA containing more excimers is beneficial to improve luminescence Cy7 acceptor via triplet-to-singlet energy transfer.
The overexpressed glutathione (GSH) in tumor cells was a crucial obstacle to improving the performance of photodynamic therapy (PDT). Complex approaches combined with different substances for PDT and GSH depletion brought potential toxic/side effects metal ions or used unsustainable disulfide bonds. Therefore, photosensitizer (PS) capable continuously depleting keeping reactive oxygen species (ROS) generation from falling simultaneously is still challenge. Here, newly designed Janus-PSs TBBr...

The Förster resonance energy transfer (FRET) process has been utilized to construct host–guest systems with stimuli-responsive room-temperature phosphorescence (RTP).
Organic room-temperature phosphorescence (RTP) materials have demonstrated great potential applications in optoelectronics, anticounterfeiting, and biomedicine fields. Among them, the RTP properties of host–guest systems can be easily regulated by changing their component parameters, which has attracted widespread attention. However, key factor hosts (crystalline or noncovalent interaction network) for boosting emission at room temperature was still unclear. Herein, a triphenyl phosphor...
Recent advancements have focused on developing nanoscale persistent room-temperature phosphorescence (pRTP) structures to expand their applicability in biomedical fields. Traditional fabrication methods typically produce surface-coated core-shell pRTP nanoparticles composed of nonbiocompatible emitters at very high concentrations the core. To overcome this limitation, polymeric nanosystems been presented study as a promising alternative by embedding RTP molecules within biocompatible polymer...
Abstract Though mechano‐responsive luminescent materials obtained much attention, most of their responses are non‐reversible, let alone in situ reversible. Here, the study presents a new strategy to push through this limitation for applications, which relies on reversible (MR) hydrogen bonding interactions and polymer chain orientation among doped polyurethane (PU) elastomer. The radiative nonradiative transitions inside these phosphorescent triphenylene‐based aromatic secondary amines (TpNP...
