Abstract	Soluble star-like branched organosilicon compounds having silanylene and oligothienylene in their arms are stable in vacuum upon light irradiation, and remain highly light emissive, but degrade upon light irradiation in air. Though the change of absorption spectrum upon light irradiation is not so large, photoluminescence (PL) intensity is strongly suppressed without notable change in spectrum shape. Remarkable shortening of PL decay time due to degradation upon light irradiation in air has been confirmed by time-resolved PL measurement. These results are discussed in terms of scission of Si–Si bonds and oxidation. Optical recording utilizing photoinduced insolubilization of these materials has also been demonstrated.
