Trans-4,4'-diaminostilbene was obtained by the reduction of Trans-4,4'-dinitrostilbene with Tin or Tin (II) chloride and hydrochloric acid by Calvin's or Albert's method. Trans-4,4'-bisacetoamidostilbene (trans-BAAS) was synthesized by the acetylation of Trans-4,4'-diaminostilbene with the mixture of acetic anhydride and acetic acid (1 : 1). The photofading of trans-BAAS in solution was examined by spectrophotometry. This photofading was accelerated in the presence of sensitizer of singlet oxygen, e.g. Rose Bengal (RB). In irradiation of filtered (λ > 420nm) light, the photofading was not observed, but by addition of RB, that fading was observed and was accelerated in the solvents which have long life time of singlet oxygen. It is suggested that the photofading of trans-BAAS in solution may be due to a selfsensitized photo-oxidation involving singlet oxygen."}, pages = {81--87}, title = {蛍光増白剤の光退色(その1) : モデル化合物の合成とその光退色}, volume = {27}, year = {1981} }
