Steric and Solvent Effect in Dye-Sensitized Solar Cells Utilizing Phenothiazine-Based Dyes

International Journal of Photoenergy, 2014
Three phenothiazine-based dyes have been prepared and utilized as dye-sensitized solar cells (DSSCs). The effects of dye-adsorption solvent on the performances of dye-sensitized solar cells based on phenothiazine dyes were investigated in this study. The

Tuning the Photochemistry of Entatic State Model Systems

Zeitschrift für anorganische und allgemeine Chemie, Volume 652, Issue 9, 3 June 2026.
We present the photochemistry of the entatic state model [Cu(DMEGqu)2]+/2+, a copper guanidino‐quinoline complex pair. By transient IR and UV/Vis spectroscopy, we obtained the lifetimes of the different excited states. We show that the structural effect of the guanidine tunes the photochemistry of this entatic state model.

A Study on Enhancing Stability and Conductivity of ZnO Through Controlled Doping

Advanced Theory and Simulations, Volume 9, Issue 6, June 2026.
First principles modelling reveals vanadium and indium as complementary tuning knobs in cubic ZnO, enabling controlled changes in optical absorption, dielectric screening, and frequency‐dependent conductivity. Moderate doping maximizes optoelectronic gain, while higher loading can trigger mechanical softening.

Stimuli‐Responsive Hydrogels for Optical Applications: Mechanisms, Architectures, and Translational Challenges

Aggregate, Volume 7, Issue 6, June 2026.
The review discusses stimuli‐responsive hydrogels as soft optical materials that translate physical, chemical, and biological cues into refractive‐index, scattering, birefringence, diffraction, and transparency changes. It examines major stimulus classes and photonic architectures for biosensing, waveguiding, adaptive lenses, smart windows, and therapy.

Ion‐Pairing and Counterion Effects in Contemporary Photochemistry

Angewandte Chemie Novit, Volume 2, Issue 2, June 2026.
Ion‐pairing and counterion effects have emerged as fundamental yet underexplored determinants of photochemical behavior. Far from inert, counterions, and Coulombic interactions modulate excited‐state dynamics, quenching efficiencies, emission, and catalytic pathways.
