In recent years, organic materials with room-temperature phosphorescence (RTP) features have gained significant attention due to their wide applications in the fields of bioimaging, light-harvesting materials, encryption technology, etc. Although several examples of organic RTP materials in the crystalline state and polymer-based systems have been reported in the last decade or so, achieving organic RTP in the solution phase, particularly in the aqueous phase has remained a challenging task. Herein in this review, we summarize the progress in this direction by highlighting design strategies based on supramolecular scaffolding and host-guest complexation and the applications of such aqueous organic RTP materials in bioimaging, sensing, etc.

BN-fused aromatic compounds have garnered significant attention due to their unique electronic structures and exceptional photophysical properties, positioning them as highly promising candidates for applications in organic optoelectronics. However, the regioselective synthesis of BN isomers remains a formidable challenge, primarily stemming from the difficulty in precisely controlling reaction sites, limiting structural diversity and property tunability. Herein, we propose a regioselective synthetic strategy that employs 2,1-BN-naphthalene derivatives, wherein selective activation of N-H and C-H bonds is achieved in conjunction with -halogenated phenylboronic acids.

Liquid is the most flexible state of condensed matter and shows promise as a functional soft material. However, these same characteristics make it challenging to achieve efficient room-temperature phosphorescence (RTP) from metal-free organic molecular liquids. Herein, we report efficient RTP from liquefied thienyl diketones bearing one or two dimethyloctylsilyl (DMOS) substituents.

Amorphous organic polymers with long-lived room-temperature phosphorescence (RTP) characteristics offer intriguing possibilities to advance information security, biological imaging, optoelectronic devices, and intelligent sensors. Despite the recent advances, access to phosphorescent polymers with excellent stretchability and shape memory performance remains a challenge. Herein, nanostructured RTP block copolymers biomimicking mussel cuticles were achieved by atom transfer radical polymerization (ATRP).

Up-recycling waste wood as a source for producing materials is crucial for sustainability. Here, we discovered that in situ thermal curing of melamine-formaldehyde resin (MF) with natural wood enhanced its room temperature phosphorescence (RTP) performance. This enhancement is due to the interaction of MF with the components in wood during the in situ thermal curing process, both covalently and non-covalently, promoting RTP emission of holocellulose and lignin in natural wood.

Organic room temperature phosphorescence (RTP) materials offer high tumor-to-background imaging contrast owing to their long afterglow and minimal autofluorescence interference. In this work, a targeted phosphorescent nanoprobe is prepared based on a pyrene/benzophenone (PyBP) guest-host system and further functionalized it with folic acid and cyclic Arg-Gly-Asp peptide for enhanced tumor specificity. In oral squamous cell carcinoma (OSCC) xenograft models, this dual-ligand nanoprobe can help achieve a four-fivefold increase in the tumor signal over the background.
