FlexMat, EarlyView.Integrating carbonyl lock onto multi‐resonant organoboron emitters is found to go beyond conventional bridge unit. It can not only suppress the molecular relaxation as conventional bridge, but also substantially affect electronic engineering via carbonyl integration, activating multiple up‐conversion channels, thus leading to an accelerated spin‐flip ...

Changes of phthalocyanine visible color caused by near-IR solvatochromism
, 2018 Herein, we show that the Zn complex of 1,4,8,11,15,18,22,28-octakis(butoxy)phthalocyanine exhibits solvatochromism and characterize the corresponding visible color changes.

Mechanophores for Mechano‐Imaging in Polymeric Materials
Helvetica Chimica Acta, EarlyView.Mechanophore‐based mechanochromic systems convert mechanical forces in polymers into optical signals, enabling direct imaging of stress localization and molecular damage. This perspective highlights recent advances in mechanophore design and their use to probe local mechanics across diverse polymer matrices, and concludes by outlining opportunities for

Synthesis and Solvatochromism of Substituted 4‑(Nitrostyryl)phenolate Dyes
, 2015 4-(Nitrostyryl)phenols 2a–9a were synthesized, and by deprotonation in solution, the solvatochromic phenolates 2b–9b were formed. Their absorption bands in the vis region of the spectra are due to π–π* electronic transitions, of an intramolecular charge-

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.

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
