• The photoreactions of hexacyanocobaltate(III) in non-aqueous solvents (methanol, ethanol, acetonitrile, DMF, pyridine) caused by irradiation at 365 nm or 313 nm are found to be the photosolvation<BR>[Co(CN)_6]^3- + Solv. \oversethν→ [Co(CN)_5(Solv.)]^2- + CN^-<BR>In pyridine, in addition to the photosolvation product, a fluorescent substance which is perhaps an aromatic compound is also formed by the irradiation at 365 nm. The quantum yields are almost the same as that in aqueous solution. In ethanol, the quantum yields irradiated at both 313 nm and 365 nm are the same, indicating that the quantum yield is independent of the exciting wavelength. The sensitized photosolvation using several donors failed to occur because of the solubility limitation. Interesting spectral results are also reported.
