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.

5,12‐TIPS‐Substitution of Tetracene: Effects on Redox Potentials and Cyclic Voltammetric Behavior in CH2Cl2 and THF1

Chemistry – A European Journal, Volume 32, Issue 18, 14 May 2026.
Tetracene and bis(tri(isopropyl)silylethynyl)tetracene (TIPS‐tetracene) exhibit characteristic similarities and differences in their electrochemical redox behavior depending on the base solvent of the electrolyte. Analysis of cyclic voltammograms allows the quantification of substituent and solvent effects and the calculation of an “electrochemical gap.

Voltage‐Gated Dedoping of n‐Doped Poly(benzodifurandione) as an Interfacial Protective Mechanism in Electrochromic Devices

Advanced Functional Materials, Volume 36, Issue 36, 4 May 2026.
Electrochromic polymer stability under overpotential is improved by inserting an ultrathin, transparent n‐doped poly(benzodifurandione) interlayer between indium tin oxide and a poly(3,4‐propylenedioxythiophene)‐based electrochromic polymer. The interlayer supports rapid switching at operating bias, then becomes resistive near +0.8 V to suppress excess

The Metamorphosis of Strongly Electron‐Accepting Dithieno[2,3‐b;3′,2′‐e]‐4‐Keto‐1,4‐Dihydrophosphinines

ChemistryEurope, Volume 4, Issue 5, May 2026.
The dithienophosphinine system is a highly versatile conjugated scaffold with strongly pronounced electron‐acceptor characteristics that lead to persistent radical anions. The electronic properties can effectively be tuned by P‐chemistry avenues and keto group modification, as well as π‐extension of the core.
