An all‐polymer blend for photovoltaic applications: A combined photoabsorption, photoemission and ab initio multi‐configurational study

Polymer International, Volume 75, Issue 10, Page 983-992, October 2026.
Near‐edge X‐ray absorption fine structure, X‐ray photoelectron spectroscopy and multi‐configuration self‐consistent field results show, respectively, preferential edge‐on and face‐on orientations for the thiophene and naphthalene diimide units of the PBDB‐T‐SF:P(NDI2OD‐T2) all‐polymer blend, and surface accumulation of the acceptor.

Structural and Functional Characterisation of a Metagenome‐Derived CYP108D18 Reveals an Unusual Dioxygen‐Bound State and Selective Hydrocarbon Hydroxylation

Microbial Biotechnology, Volume 19, Issue 10, October 2026.
CYP108D18, identified from a hot spring metagenome, catalyses selective phenylcyclohexane hydroxylation. This P450 has an exceptionally low substrate‐bound heme redox potential. Crystal structures revealed an unusual dioxygen‐bound substrate‐free form and a persistent open active site upon substrate binding.

Lysosome‐Targeted Squaramide Anion Transporters

Chemistry – A European Journal, Volume 32, Issue 36, 24 September 2026.
Lysosome‐targeted squaramide anion transporters elicit different biological effects depending on the targeting group employed. ABSTRACT Targeting anion transporters to specific organelles has previously been shown to be an effective strategy to enhance their cytotoxicities against cancerous cell lines.

Modular π‐Extended IF‐TTF Systems: Tuning Redox and Optical Properties in Donor–Acceptor and Donor–Donor Frameworks

European Journal of Organic Chemistry, Volume 29, Issue 36, 24 September 2026.
Donor–acceptor and donor–donor systems incorporating an indeno[1,2‐b]fluorene‐extended tetrathiafulvalene (IF‐TTF) donor motif were prepared by Suzuki coupling reactions. The compounds were studied for their optical and redox properties. The compounds showed multiredox behavior with several accessible redox states. A series of π‐extended donor–acceptor
