Photochemistry of organoselenium compounds
Irradiation of dibenzyl diselenide (l) with 350 nm light in the presence of oxygen afforded benzaldehyde and elemental selenium, whereas irradiation in the absence of oxygen produced dibenzyl monoselenide (ll); irradiation of dibenzyl triselenocarbonate (III) produced dibenzyl diselenide.
Transparent inorganic-organic film with nanoparticle shows promising application in various technology field. In order to obtain transparent inorganic-organic composite film, the main challenge is to homogeneously disperse inorganic nanoparticle in polymer matrix without coagulation. This study demonstrated that silane-modification can obtain ZrO2 with chemically bonded silane. The ZrO2 nanoparticle shows good stability in various organic phase. Thus prepared inorganic-organic composite film has transparence as high as 80%.
