Acyclic Diene Metathesis (ADMET) Polymerization of 2,2,6,6‐Tetramethylpiperidine‐1‐sulfanyl (TEMPS) Dimers

Abstract

Inside Cover: Marrying acyclic diene metathesis polymerization and BiTEMPS chemistry offers a simple method to prepare a tailor‐made polymer with precise control over the primary structure. Pivotally, the macromolecule, decorated with sulfur‐nitrogen bonds in each repeating unit, exhibits light‐responsive reversible homolytic dissociation of disulfide linkage, where the specific treatment (e.g., anaerobic condition) is not required. The latter allows reorganization of the polymeric architecture on exposure to the stimulus, and this molecular‐based response is foreseen to be translated to the macroscopic scale. This work is found in article number 2100118 by Hatice Mutlu and co‐workers.

Electrochemical Investigations of Sulfur‐Decorated Organic Materials as Cathodes for Alkali Batteries

“…Organic materials, BiTEMPS‐OH and thiophene/arene copolymer (TAC), as shown in Figure , were synthesized using the same methods previously reported by Mutlu and colleagues [ 27 ] (The detailed methods are listed in the Supporting information). The respective chemical structural characterization performed via nuclear magnetic resonance (NMR) was in line with the reported data, demonstrating that both synthesized materials were pure (Figure S1–S6, Supporting information).…”

A thermally driven rotaxane–catenane interconversion with a dynamic bis(hindered amino) disulfide

“…Recently, we have developed a method for the selective isolation of macrocycles that contain bis(2,2,6,6-tetramethylpiperidin-1-yl) disulfide (BiTEMPS [25][26][27] ) units in their cyclic structure. 28 The BiTEMPS unit is a dynamic moiety, whose disulfide linker can exchange with other disulfides merely upon heating to ∼100 °C.…”
