ResumoExtended π-conjugated systems and tunable optic properties are characteristic for compounds with linear backbones based on electron-donating thiophene, electron-accepting pyridine, and a σ3,λ3-phosphole core. The oligomers 1 and 2 are fluorescent chromophores and, for 2, these properties are tunable through chemical modification of the phosphorus-bound chalcogen atom. The σ4,λ4 derivatives of 2 are electropolymerized to electroactive polymers. Y=lone electron pair, or O, S, or Se atom.
