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 ...

Self‐Immolative Gels: Programmable Degradation Using Self‐Immolative Linkers and Polymers

Chemistry – A European Journal, Volume 32, Issue 23, 16 June 2026.
Self‐immolative linkers and polymers undergo bond‐cleaving reaction cascades in response to specific stimuli. Their incorporation into gels can be harnessed to release cargo, induce property changes, or trigger degradation in a highly controlled manner. These functions can be employed in applications such as sensing and drug delivery.

Effect of carbon hybridization in 9H-fluorene unit on the photovoltaic properties of different fluorene-based conjugated polymers

, 2017
To investigate the effect of different carbon hybridization in 9H-fluorene on the resultant polymers, a series of donor–acceptor conjugated polymers have been synthesized by copolymerizing substituted 9H-fluorenes with triazoloquinoxaline.

Precisely Controlled Electrochemical Phosphonylation: Tailoring π‐Conjugated Polymer Properties for High‐Performance Organic Electrochemical Transistors

Angewandte Chemie, Volume 138, Issue 23, 1 June 2026.
The electrochemical C–H phosphonylation enabled precise control over the degree of functionalization (DOF). Systematic tuning of DOF (0.06–0.16) led to improved µC*, transconductance, and time constant values. This finding demonstrates that moderate functionalization enhances organic electrochemical transistor (OECT) performance, opening new avenues ...

Remarkable Formation of Indene Derivatives Upon Friedel–Crafts Acylation Reactions

European Journal of Organic Chemistry, Volume 29, Issue 23, 16 June 2026.
This shows indene derivatives. Under the reaction conditions of a Friedel–Crafts acylation, alkyl benzenes underwent an unprecedented cyclopentannulation furnishing indene derivatives. Alkylbenzene derivatives react with two equivalents of pivaloyl chloride (PivCl) in the presence of aluminum trichloride under formation of indene derivatives with up to
