A photocreated metastable state in organopolysilanes has been studied using the electron spin resonance technique. Depending on the excitation photon energy, two different kinds of signals have been observed for the first time. The origin of the signals are discussed, in comparison with a first principles calculation. As a result, the self-trapping of an electron and the sodium related defect creation are suggested in organopolysilane depending on the excitation energy. These results are compared with the Staebler-Wronski effect in a-Si:H.
