Optical imaging of diseases represents a highly dynamic and multidisciplinary research area, second near-infrared window (NIR-II, 1000-1700 nm) is at the forefront on optical techniques. Small-molecule based NIR-II (1000-1700 dyes are promising candidates for in vivo molecular because their high biocompatibility, fast excretion, clinical translation ability. However, reports small-molecule probes rare. Herein, we designed series fluorescent compounds (Q1, Q2, Q3, Q4) investigated...

Abstract Recently, a remarkable advance has been made for metal‐free room‐temperature phosphorescence (RTP) crystals with high quantum yield. However, amorphous, especially heavy‐atom‐free, RTP materials still suffer from low yield due to the transition‐forbidden character of and relatively poor suppression nonradiative transition in amorphous materials. In this study, series single‐benzene structure‐based intersystem crossing phosphor is obtained. After embedding into polyvinyl alcohol...
Ultralong room temperature phosphorescence could be generated after adding trace-specific ingredients into organic compounds.
Small-molecule fluorescence imaging in the second near-infrared (NIR-II, 1000–1700 nm) window has gained increasing interest clinical application. Till now, very few studies have been exploited small-molecule fluorophores with both excitation and emission NIR-II window. Inspired by indocyanine green structure, a series of polymethine dyes absorption developed for imaging, providing feasibility to directly compare optical NIR-IIa (1300–1400 subwindow under 1064 nm that 808 excitation.

The developments of pure organic room-temperature phosphorescence (RTP) materials with circularly polarized luminescence (CPL) have significantly facilitated the future integration and systemization luminescent material in fundamental science technological applications. Here, a type photoinduced RTP are constructed by homogeneously dispersing phosphorescent chiral helical substituted polyacetylenes into processable poly(methyl methacrylate) (PMMA) matrix. These play vital roles propagation...
ConspectusThe phosphorescence is produced by the radiative transition of excited triplet state which generated intersystem crossing (ISC) from singlet state. Compared with fluorescence, it has a longer luminescence lifetime and larger Stokes shift, so phosphorescent materials have great application value in fields such as displays, anticounterfeiting, imaging. But due to low ISC rate organic molecules, slow state, large nonradiative energy loss caused molecular vibration, pure room...
Abstract Supramolecular organic framework (SOF) has recently garnered significant research interest in the field of luminescent materials. However, SOF with room‐temperature phosphorescence emission solution is very rare due to quenching dissolved oxygen and free molecular motions, which would lead nonradiative deactivation triplet exciton liquid state. In this work, a 3D cationic phosphorescent synthesized through host‐guest interaction between CB[8] tetrahedral monomer TBBP, can rapidly...
Abstract Pure organic room‐temperature phosphorescence (RTP) materials are useful for photoelectric, biochemical devices, and bioimaging sensors. In the last few years, dynamic covalent chemistry has aroused substantial attention as it offers a way to create intelligent with feedback response functions. Through Diels–Alder reaction, [4+2] cycloaddition reaction between dienes dienophiles, three polymers were synthesized that can be reversibly transformed by thermally reversible bonds. All...
In this work, a universal strategy for solid, solution, or gel state organic persistent luminescent materials via radiative energy transfer is proposed. The luminescence (τ>0.7 s) could be remotely regulated between different colors by controlling the isomerization of acceptor. function relies on simple (reabsorption) mechanism, rather than complicated communication excited molecules such as Förster resonance Dexter transfer. And "apparent lifetime" acceptor same lifetime donor, which was...
Traditional luminescent materials including fluorescent probes suffer from notorious aggregation-caused quenching (ACQ) in aqueous solutions. Although several approaches such as the aggregation-induced emission (AIE) effect have been developed, it remains a significant challenge to identify an effective and efficient strategy resolve this issue. Herein, quaternary ammonium salts Q8PBn Q8PNap novel class of bright near infrared window II (NIR-II, 1,000 - 1,700 nm) were designed synthesized,...
