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 ...

Acetylene Functionalization of Multiple‐Resonant Materials Enabling Strong Two‐Photon Absorption and Delayed Luminescence With Highly Efficient Exciplex‐Sensitized Electroluminescence

Advanced Optical Materials, Volume 14, Issue 34, 11 September 2026.
Multiple‐resonance thermally activated delayed fluorescent (MR‐TADF) material absorbs two near‐infrared 760 nm photons with cross‐section up to 156 GM, emit 26 nm narrowband green light at 491 nm with unity luminescence quantum yield and electroluminescence efficiency up to 25.2% in organic light‐emitting diode.

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 ...

Revealing Mechanofluorochromism and Intricate Long‐lived Decay Pathways in Keto‐Coumarin‐Based Molecular Crystals

Advanced Optical Materials, Volume 14, Issue 35, 18 September 2026.
Donor–acceptor organic emissive materials show great promise in cutting‐edge optical applications. Herein, the photophysical properties of two keto‐coumarin organic materials are studied in detail. Both show mechanofluorochromism, but a diphenylamine donor derivative exhibits intricate decay pathways in the crystal form, including decays ranging from ...

Water‐Enabled Ultralong Full‐Color Organic Phosphorescence in Hydrogen‐Bonded Frameworks for 4D Encryption and Bio‐Imaging

Advanced Science, Volume 13, Issue 50, 7 September 2026.
Water‐induced quenching challenges organic RTP materials, but a counter‐intuitive strategy employs HOF to encapsulate carbonyl guests, where water functions as a structural reinforcer. This achieves water‐enhanced ultralong RTP with full‐color emission (blue to deep red), overcoming intracellular quenching for high‐signal cellular imaging, alongside 4D
