Substitution‐Dependent Modulation of Photophysical Properties of 2,7‐ and 3,6‐Dinaphthyl‐9‐phenylcarbazoles in Solution and Solid State

ChemPhotoChem, Volume 10, Issue 3, March 2026.
The photophysical properties of dinaphthyl‐substituted 9‐phenylcarbazoles strongly depend on substitution geometry. 2,7‐isomers (27DNpPCz) show much faster fluorescence rates than 3,6‐isomers (36DNpPCz). Time‐dependence density function theory (DFT) calculations reveal that delocalized frontier orbitals and large oscillator strengths in 2,7‐isomers ...

Upcycling Agricultural By‐Product: Therapeutic Potential of Oriental Melon Stem (Cucumis melo var. makuwa) in Treating Obesity and Fatty Liver via Enhanced Thermogenesis

Food Frontiers, Volume 7, Issue 2, March 2026.
This study proposes the upcycling of oriental melon (Cucumis melo var. makuwa) stems, typically discarded as agricultural waste, into a bioactive extract with functional potential. CMSE ameliorates high‐fat‐diet‐induced obesity and fatty liver, contributing to the restoration of metabolic health by enhancing the expression of thermogenesis‐related ...

Host‐Guest Doping Enables Room Temperature Phosphorescence from Triarylboranes

Angewandte Chemie, Volume 138, Issue 9, 23 February 2026.
While pure triarylboranes show RTP in annealed PMMA films, they do not in crystalline form, contrary to our previous report. However, crystalline host‐guest triarylborane systems show persistent afterglow up to 8 s even at 1 ppb guest loading. Computations identify triplet‐triplet energy transfer as the mechanism governing this efficient RTP.

Defect‐Passivating and Dense Indolocarbazole‐Based Self‐Assembled Monolayers for Efficient Inverted Perovskite Solar Cells With over 26.1% Efficiency

Small, Volume 22, Issue 16, 17 March 2026.
This study proposes a strategy to modulate nitrogen positions (meta‐/para‐) in indolocarbazole units and the number of anchoring groups (mono‐/bis‐phosphonate), achieving a remarkable PCE of 26.12%, among the highest reported for PSCs using indolocarbazole‐based SAMs as HTLs.

Predictive, Data‐Driven Design of Red‐Light Photoredox Catalysts for C─Heteroatom Bond Formation

Angewandte Chemie, Volume 138, Issue 9, 23 February 2026.
From redox numbers to red light: Donor oxidation and core reduction potentials predict E0‐0 in cyanoarene dyes, guiding selection of an efficient red‐light catalyst, 4MeODPATPN (PC13). Under 620 nm light, PC13 facilitates Ni‐catalyzed C─heteroatom cross‐couplings (C─N, C─O, C─S) with high functional‐group tolerance and reduced hydrodehalogenation ...

Functional polymer materials containing heavy group‐14 elements focusing on germanium and tin

Smart Molecules, Volume 4, Issue 1, March 2026.
The synthesis, functions, and applications of the polymers containing heavy group 14 elements focusing on germanium and tin are outlined. Owing to their large atomic radii and weak binding energies, the polymers show unique properties: chromism, luminescence, carrier mobility, and reactivity to produce radials and higher coordinated states.

Tuning Covalent Organic Frameworks via Nucleophilic Aromatic Substitution

Small Science, Volume 6, Issue 3, March 2026.
The direct nucleophilic aromatic substitution reaction on a fluorinated covalent organic framework leads to functional materials bearing bulky pendant groups such as carbazole or ferrocene. The method is versatile, suitable for O‐, S‐, and N‐based nucleophiles, and provides a unique conjugated structure containing electron‐withdrawing fluorine atoms ...
