UV‐activated hydrosilylation of (Me‐Cp)Pt(Me)3: Enhanced photocatalytic activity, polymerization kinetics, and photolithography

Abstract: Hydrosilylation is commonly known as a thermally induced addition reaction between unsaturated bonds and Si H bonds to synthesize or crosslink organosilanes and organosilicones, while it has emerged that it can also be activated under the coaction of UV irradiation and specific platinum catalyst. For higher photopolymerization conversion, excessive platinum catalyst is always required; however, this inevitably causes the significant increase of production cost and decrease of operation time. In this study, tra… Show more

“…Recently, Xiang et al studied the influence of several other photosensitizers on photohydrosilylation in the presence of the same catalyst (63) in order to decrease the required Pt concentration 44 . First, they studied the reaction between divinyl-PDMS (1) and poly(methylhydrogenosiloxane) (15) under UV light (365 nm LED, 33 mW/cm 2 ) at different catalyst concentrations (50 -400 ppm, corresponding to 30 -245 ppm of Pt content).…”

“…Still, low resolution could be noticed. Si-H conversion after 100 sec of UV-activated (365 nm) hydrosilylation vs concentration of photosensitizers (see Figure 6 for the structures) 44 . Lines are only guides for the eyes.…”
