WebAug 27, 2024 · Introduction. In sharp contrast to pyrrole, which is a planar and strongly aromatic heterocycle, its immediately heavier analogue, phosphole, is characterized by a highly pyramidalised arrangement of the substituents around the phosphorus and, as consequence, a severely diminished degree of aromaticity. 1 This geometry is adopted … WebMar 13, 2003 · Novel π-conjugated polymers 10a−c having the phosphole unit were prepared by palladium complex-catalyzed coupling of bis(p-bromophenyl)phosphole (7) with diethynylarenes 9a−c. The obtained polymers 10a−c were regio-regulated with the 2,5-substituted phosphole unit and characterized by 1H and 31P NMR. Polymers 10a−c were …
