Redox‐Active Guanidines

ChemElectroChem, Volume 13, Issue 12, 17 June 2026.
Redox‐active guanidines, comprising guanidino‐functionalized aromatics (GFAs) and redox‐active urea azines (RAAs), are electron donors and strong Lewis and Brønsted bases that are used in several applications. They act as redox‐active ligands in bistable coordination compounds and as reagents in dehydrogenative coupling reactions and proton‐coupled ...

Dilithium manganese(II) catena-tetrakis(polyphosphate), Li2Mn(PO3)4

Acta Crystallographica Section E, 2014
The poly-phosphate Li2Mn(PO3)4 was synthesized and its structure characterized from powder diffraction data by Averbuch-Pouchot & Durif [J. Appl. Cryst. (1972), 5, 307–308]. These authors showed that the structure of this phosphate is isotypic to that of

Aryl Viologen Polymers in High‐Voltage Full‐Organic Batteries

Advanced Energy and Sustainability Research, Volume 7, Issue 3, March 2026.
A series of aryl‐viologen polymers is synthesized, and their performance in battery half‐cells is investigated. Pairing the best‐performing polymer with a phenothiazine‐polymer positive electrode creates a full‐organic battery with a high discharge voltage of up to 1.8 V and a specific discharge capacity of 78 mAh g−1.

Trapping an Aryl‐substituted Borete Intermediate in Catalyst‐free 1,5‐Diborocine Synthesis

European Journal of Inorganic Chemistry, Volume 29, Issue 4, February 1, 2026.
A transient aryl‐substituted borete was trapped as its adduct with 4‐(dimethylamino)pyridine (dmap) and fully characterised. While the dmap adduct is highly kinetically stable, the free borete could not be observed in the absence of dmap. Density‐functional calculations support a rapid dimerisation of the borete via (4 + 4) cycloaddition, yielding a 1 ...
