Asymmetric Diphosphane Dioxides With A–π–A–π’–D Scaffolds for High‐Purity Deep‐Blue Luminescence

Chemistry – A European Journal, Volume 32, Issue 36, 24 September 2026.
Diphosphane dioxide‐based luminophores with donor–π–acceptor– π’–acceptor scaffold enable efficient deep‐blue emission from tunable charge‐transfer states affording high photoluminescence up to 95%. OLEDs reach EQE 4.9%, aided by triplet–triplet annihilation, highlighting a practical route to high‐performance blue emitters.

Stacking the Deck to Make Materials With Atypically Short Heterometallic d8 M(II)···Au(III) Bonds

Angewandte Chemie, Volume 138, Issue 37, 7 September 2026.
Tetracyanoplatinate(II) and tetracyanoaurate(III), through self‐assembly in the presence of KCl, crystallize from water to form a one‐dimensional chain featuring the first reported PtII···AuIII metallophilic interaction with a very short distance of ∼3.0 Å between the metal centers.

Effects of Mono‐ and Dicapsaicinoid Functionalization on the Physicochemical Properties and Antimicrobial Photodynamic Activity of Protoporphyrin IX

ChemMedChem, Volume 21, Issue 17, 14 September 2026.
Capsaicin functionalization of Protoporphyrin IX influences aggregation behavior, lipophilicity, and photodynamic activity. A monosubstituted derivative exhibits enhanced antimicrobial photoinactivation of Staphylococcus aureus, whereas increased functionalization does not improve efficacy.

Changing N^C^O to C^N^O Coordination in Cyclometalated Pt(II) and Pd(II) Complexes Modulates Stability and Emission Characteristics: Toward Brighter Versatility

Chemistry – A European Journal, Volume 32, Issue 34, 11 September 2026.
A new class of cyclometalated metal complexes with pincer luminophores (C^N^O and N^C^O) is reported. They unite high photoluminescence efficiencies in liquid solutions at r.t. with tunable colors across the visible spectrum and convenient synthetic accessibility.

Synthesis and Functional Properties of Fluorinated Phosphonate‐Substituted Porphyrins: Excellent Photosensitizers and Robust Precursors for Photoactive Langmuir–Schaefer Films

Chemistry – A European Journal, Volume 32, Issue 34, 11 September 2026.
This is a comprehensive study of new family of high functionalized meso‐tetraarylporphyrins. A synthetic approach to phosphonate‐substituted fluorinated porphyrins was developed. These compounds were investigated with respect to singlet oxygen generation and photostability.

Development of a Multi‐Organ Microphysiological (MPS) Model to Study Age‐Related Comorbidities

Advanced Biology, Volume 10, Issue 9, September 2026.
This study developed a human‐based organ‐on‐a‐chip model for the comorbidity of sarcopenia and hypertrophic cardiomyopathy (HCM). The microphysiological system (MPS) co‐cultured skeletal muscle of sarcopenia pathology, cardiomyocytes of HCM pathology, and healthy hepatocytes in a circulated serum‐free common medium.

Chiral Porphyrin Monolayers on Ferromagnetic Thin Films: Ultrafast Spectroscopy of Hybrid Interfaces

Advanced Optical Materials, Volume 14, Issue 33, 4 September 2026.
Chiral porphyrin–oligopeptide monolayers covalently bound to Au‐capped Co/Ni multilayers form surface‐parallel J‐type aggregates and exhibit measurable singlet‐state transient absorption despite monolayer coverage. Femtosecond pump–probe spectroscopy reveals strong excited‐state quenching at the metal interface, yet no long‐lived charge‐transfer ...

Tailoring Amine Substitution in Fluorene and Dibenzothiophene: A Molecular Strategy for Ultralong Organic Phosphorescence

Advanced Optical Materials, Volume 14, Issue 35, 18 September 2026.
Tailored amine substitution in fluorene and dibenzothiophene derivatives enables systematic control of excited‐state properties and triplet population. Combined photophysical studies, TD‐DFT calculations and time‐resolved EPR reveal how charge‐transfer character, sulfur‐induced spin–orbit coupling and triplet manifold engineering cooperate to promote ...
