General description

Diphenylsilanediol(DPSD) is an alkoxysilane that is used as a silane based precusor in the synthesis of organosiloxane based resins.

Application

DPSD may be used as a precursor in the synthesis of linear vinyl oligosiloxane resins which can be potentially used in the fabrication of thermally resistant light emitting diode(LED) encapsulant. Mercaptopropyl-phenyl-oligosiloxane and phenyl-vinyl-oligosiloxane may be synthesized by using DPSD which can further be used as a thiolene derived dielectric layer for organic thin film transistors.

Metal nanowires (NWs) are promising transparent conducting electrode (TCE) materials because of their excellent optoelectrical performance, intrinsic mechanical flexibility, and large-scale processability. However, the surface roughness, thermal/chemical instability, and limited electrical conductivity associated with empty spaces between metal NWs are
