Carbonized polymer dots with aqueous‐stable room‐temperature phosphorescence: Mechanism, matrix engineering, and application

Responsive Materials, EarlyView.
This review focuses on inorganic and organic matrices that enable aqueous‐stable room‐temperature phosphorescence (RTP) in carbonized polymer dots (CPDs). It explains the underlying RTP mechanisms, highlights how matrix engineering provides spatial confinement and bonding interactions to stabilize triplet excitons in water, and demonstrates key ...

White light emitting molecular logic gates

Smart Molecules, EarlyView.
White light emitting smart molecules with Boolean logic computing ability are surveyed. Abstract White light emitting (WLE) materials are of considerable interest with commercial and societal applications in video displays and lighting devices. A characteristic property of WLE materials is the luminescence profile spanning from 380 to 700 nm.

Molecular Persistent Room-Temperature Phosphorescence from Tetraarylaminoboranes

Herein, we report the synthesis, molecular structure, and optical features of tetrarylaminoboranes 1 (Mes2B-N­(Ph)­(C10H7)) and 2 (Mes2B-N­(Ph)­(C14H9)). In the solution state, 1 shows aggregation-induced emission enhancement and color switching, while 2

Force‐Induced Control of Circularly Polarized Luminescence With Rotaxane Architecture

Angewandte Chemie, Volume 138, Issue 39, 21 September 2026.
Force‐induced reversible on/off switching of circularly polarized luminescence is achieved with a rotaxane‐based supramolecular mechanophore. The mechanophore, featuring a chiral helicene luminophore, is incorporated as a first network cross‐linker into a double‐network organogel.

Dual room‐temperature phosphorescence derived from the reversible homolysis in the high proportion n‐electron organic crystal

Smart Molecules, EarlyView.
[2,2′‐biisoindoline]‐1,1′,3,3′‐tetraone (4A2B) crystal with high n‐electrons undergoes photo‐induced reversible homolysis resulting in two room‐temperature phosphorescence (RTP). One of the 4A2B molecules responds strongly to 250 nm via fast intersystem crossing (ISC) processes among high‐lying excited states.

Emission Tuning of Group 13 DPP‑ Pincer Complexes via the Heavy Atom Effect of the Metal Ion and the Halide Ligands

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.
The complete series of all nine variations of complexes (DPP)MX2 (DPP = 2,5‐di(pyridin‐2‐yl)pyrrolide; M = Al, Ga, In; X = Cl, Br, I) reveals that the heavy atom effect of both the metal ion and the halide ligands promote ISC, giving rise to dual fluorescence and phosphorescence emission at 77 K. We report on the synthesis, structural characterization,
