Poly(diaryl)stannanes:  Influence of Substituents on the σ−σ Transition Energy

Poly(diaryl)stannanes were prepared by the dehydropolymerization of secondary hydrostannanes Ar2SnH2 with dimethylzirconocene catalyst. At room temperature, H(Ar2Sn) n H polystannanes (Ar = p- t Bu-C6H4, p- n Hex-C6H4, o-Et-C6H4, o-Et-p- n BuO-C6H3, p- n BuO-C6H4, p-(Me3Si)2N-C6H4) exhibit λmax valu...
