On‐Surface Synthesis and Characterization of Cumulene‐Linked Stone‐Wales Polymers
Angewandte Chemie, EarlyView.On‐surface synthesis of one‐dimensional polymers featuring Stone‐Wales defects and cumulene linkages is demonstrated via thermally and light‐induced reactions on Au(111). STM, nc‐AFM, and Raman spectroscopy, complemented by theory calculations, reveal their chemical structure with a non‐planar geometry, and a distinct electronic bandgap of 1.8 eV ...

Covalent Bond Regulation in Nanographene: En Route to Precise Aggregation State Modification
Aggregate, EarlyView.Regulation of nanographene from covalent bond to control the aggregation state of nanographene precisely was achieved by protonic acid or Lewis acid. The fused azulene unit(s) at the margin of molecules played an important role for the unique chemical activity and physical features. Furthermore, quencher and reaction temperature would lead to selective

Hinge‐Like Mechanochromic Mechanophores Based on [2.2]Paracyclophane
Angewandte Chemie, EarlyView.Hinge‐like supramolecular mechanophores utilizing [2.2]paracyclophane have been developed. In the force‐free state, the rigid [2.2]paracyclophane forces two luminophores into proximity, leading to excimer‐dominant photoluminescence. Stretching the polyurethane films into which the mechanophores are covalently incorporated results in the structures of ...

Angewandte Chemie, EarlyView.A robust molecular design strategy for MR‐TADF emitters via heterocyclic carbazole integration to strengthen weak C─N bonds was proposed. Blue MR‐TADF emitters m‐Cz‐DABNA and tBu‐Cz‐DABNA have achieved ultra‐narrow FWHMs (24/21 nm), high PLQYs (88%/95%), and record‐high EQEs (23%/26%).
