A facile method for the quantitative preparation of silver dibenzo-fused corrole Ag-1 is described. In contrast to the saddle conformation resolved by single-crystal X-ray analysis for Ag-1, it adopts an unprecedented domed geometry, with up and down orientations, when adsorbed on an Ag(111) surface. Sharp Kondo resonances near Fermi level, both at the corrole ligand and the silver center were observed by cryogenic STM, with relatively high Kondo temperature (172 K), providing evidence for a non-innocent Ag II -corroleC 2À species. Further investigation validates that benzene ring fusion and moleculesubstrate interactions play pivotal roles in enhancing Ag(4d-(x 2 Ày 2 ))-corrole (p) orbital interactions, thereby stabilizing the open-shell singlet Ag II -corroleC 2À on Ag(111) surface. Moreover, this strategy used for constructing metal-free benzene-ring fused corrole ligand gives rise to inspiration of designing novel metal-corrole compound for multichannel molecular spintronics devices.

A highly stable 16π-electron antiaromatic system based on a monocationic tetrabenzocorrole Cu(ii) complex is reported.

A series of benzo[a]-fused BODIPYs and the corresponding isomeric naphthyl-BODIPYs have been synthesized through a facile one-pot palladium-catalyzed domino reaction of BODIPY precursors (2-bromo-BODIPYs) with diarylethynes.

A new class of BOPPY derivatives has been facilely synthesized by a two-step reaction of coupling 3,5-dimethylpyrrole-2-carbaldehyde with 2,3-dihydrazinoquinoxaline (QDH) followed by coordinating with BF3·OEt2. The reaction mainly produces a...
