thiophene, furan or pyrrole. However, they exhibit another form of conjugation (σ* π*-conjugation or rather hyperconjugation) instead, which leads to unique (opto)electronic properties. This conjugation is [...] is very low in their carbon analog, but replacement of the methylene part by a stannylene (or rather a silylene, germylene or plumbylene) moiety strengthens the conjugation extremely. Due to the efficient
