General description

Dichlorodiphenylsilane is a silane based surface modifier, and a precursor which can be used in the synthesis of silica based materials. It is used to modify the surface by providing toughness, durability and resistance to shock.

Application

Dichlorodiphenylsilane can be used in the synthesis of a host material for the fabrication of blue phosphorescent organic light emitting diodes (OLEDs).
The addition reaction of dichlorodiphenylsilane with diglycidyl ether of bisphenol-S yields poly(silyl ether) with pendant chloromethyl groups. {40} The coupling reaction between dichloromethylsilane and dichlorodiphenylsilane can form diorganosilane-hydrosilane copolymers at -75oC. Heating the compound with tetrabutoxydianilinocyclophosphazene at temperatures between 100oC-160oC may yield cyclophosphazene oligomers.{42}
