ИСТИНА

Recently molecules containing non-carbon chain atoms, such as Ge, Si, Sn (E), attract significant attention as perspective materials for "organic electronics". Electrons of the single E-E bond are delocalized over the entire chain of atoms of elements (σ-conjugation). Thus, the existence of σ-delocalization in such derivatives leads to the appearance of properties which are characteristic for unsaturated hydrocarbons (conductivity, thermochromism, non-linear optical properties, luminescence etc.). In our scientific group we investigated the synthesis and properties of catenated derivatives of Group 14 elements containing various substituents (electron withdrawing/electron donating groups with different volume).
