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.

A Blue Emissive Heavy Atom‐Free Multiresonant Thermally Activated Delayed Fluorescent Emitter Shows Ultra‐Fast Reverse Intersystem Crossing

Angewandte Chemie, Volume 138, Issue 38, 14 September 2026.
The extended π‐system and low‐lying n‐π∗ transition endow DDOBDiKTa with a synergistic combination of strong spin‐orbit coupling, small reorganization energy and small ΔEST, enabling this blue boron‐nitrogen‐carbonyl hybrid emitter to achieve a fast kRISC of 6.34 × 106 s−1 together with OLEDs showing small efficiency roll‐off, with EQEmax/EQE10000 of ...

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,
