Hybrid Quatsome‐Encapsulated Silver Nanoparticles as Stable Plasmonic Substrates for Surface‐Enhanced Raman Scattering

Journal of Raman Spectroscopy, EarlyView.
In this work, silver nanoparticles encapsulated within quatsome membranes have shown to preserve their plasmonic properties for at least 165 days without aggregation. These hybrid nanostructures enable strong SERS enhancement of pyrene and Prodan by confining the molecules within a few nanometers from the silver surface.

Light and Dark Cycles Control the Structural Evolution of Photoresponsive Supramolecular Systems

Angewandte Chemie, Volume 138, Issue 31, 27 July 2026.
Here, we report a photoswitchable synthetic peptide that, under light energy cycles, exhibits supramolecular polymorphism coupled to darkness‐driven structural self‐selection. We demonstrate that light sustains a transient assembled state in the form of helical nanoribbons, hindering the system from undergoing a transition to the disassembled state ...

A green solvent processable, self‐doped N‐annulated perylene butyl tetraester applied as a solar cell cathode interlayer

Polymer International, EarlyView.
A new organic molecular cathode interlayer is presented built upon the perylene butyl tetraester scaffold. The new molecule incorporates N‐annulation and a functional amine group to control optical, electrochemical and physical properties and delivers excellent solar cell performance. Abstract We report a new amino‐bay‐substituted, N‐annulated perylene

A BODIPY-Bridged Bisphenoxyl Diradicaloid: Solvent-Dependent Diradical Character and Physical Properties

Molecules, 2019
We report a new boron dipyrromethene (BODIPY)-bridged bisphenoxyl diradicaloid (2), which showed closed-shell diamagnetic character in less polar solvents such as dichloromethane but open-shell diradical character with paramagnetic activity in the very ...

Humidity‐Guided In Situ Polymerization for Controlled Formation of Smooth, Oriented Covalent Organic Framework Films

Small, EarlyView.
We develop an operationally simple, efficient approach to prepare thin films of 2D imine COFs, where environmental humidity plays a key role in the formation of smooth, face‐on oriented films. The high controllability and reproducibility of this method allow statistical evaluation of morphologically varied COF films for chemiresistive sensing ...

High‐performance electro‐optic materials featuring enhanced thermal stability through dual‐donor structural crosslinking engineering

Smart Molecules, EarlyView.
A groundbreaking dual‐donor crosslinking strategy was reported to significantly enhance the thermal stability, achieving remarkable EO coefficients (257–301 pm/V), glass transition temperatures (Tg) ranging from 107–187°C, and ultrahigh chromophore densities (3.73–4.26 × 10²⁰ molecules/cm³) with exceptional long‐term stability after 500 h at 85°C ...

Planarized and Twisted Intramolecular Charge Transfer: Small Geometric, Huge Photophysical Changes

European Journal of Organic Chemistry, Volume 29, Issue 29, 7 August 2026.
Molecular motion governs excited state relaxation in aminobenzonitrile donor–acceptor systems. Small structural modifications control single and dual rotations and enable distinct relaxation pathways. Fluorescence spectroscopy, Lippert–Mataga analysis, and theoretical calculations identify multiple excited states, including a dual‐emitting planarized ...

The Synthesis Use of a Difluorinated Amino‐Benzo‐Cinnoline Dyes (ABCDyes) Enables Fine Tuning of Emission Through Double SNAr Late‐Stage Functionalization

European Journal of Organic Chemistry, Volume 29, Issue 29, 7 August 2026.
An efficient synthesis of difluorinated amino‐benzo‐cinnoline dyes (ABCDyes) is reported. Their use for the late‐stage introduction of internal dinucleophilic species through a double SNAr reaction enables straightforward access to previously unexplored ABCDye analogs displaying tunable emission ranging from green to red.
