Photosensitive silicon-containing poly(salicylideneazomethynes) have been synthesized. It has been shown that these polymers are characterized by the presence of intramolecular donor-acceptor interactions between valence shells of silicon and nitroge

Photophysical properties of new silicon-containing “nonclassical” polyconjugated poly[salicylidene azomethine]s were studied and a free carrier photogeneration mechanism characteristic of them was proposed. It was shown that polymer properties ar

New silicon-containing poly(salicylidene azomethines) were prepared by polycondensation of di-or tetrasalicylidene derivatives of aromatic di- or tetraamines. The spectral data suggest the occurrence of noncovalent transannular donor-acceptor interac

It is shown that cyclic oxides can be anionically polymerized if the lowest vacant molecular orbital (LVMO) of a Cα atom contains a region which can effectively overlap by the electronic cloud of the anionic active centre. This means that LVMO must
