Abstract
A method of producing a polymer composition for semiconductor optoelectronics, comprising the steps of providing at least one type of disilane monomer which is homo- or copolymerized to form a (co)polymer and then combined with nanoparticles to provide a polymer composition. The nanoparticle containing composition has excellent properties with high refractive index or dielectric constant.

A method for producing a polymer composition for semiconductor optoelectronics, comprising the steps of
- providing a monomer having the formula:
- (R1)xSi(R2)y or Ia
- (R1)xSi—R3—Si(R2)y IIa
- wherein:
- R1 is a hydrolysable group
- R2 is a functional organic group,
- R3 is an optional bridging linear or branched bivalent hydrocarbyl group, and x and y are integers from 1 to 3,
- homo- or copolymerizing the monomer to produce a polymer or copolymer, and
- combining the polymer or copolymer with nanoparticles to provide a polymer composition.
A method of producing a thin film for optoelectronics comprising depositing on a semiconductor substrate a film obtainable by polymerization of an organo functionalized monomer having the formula:
- (R1)xSi(R2)y Ia
- or
- (R1)xSi—R3—Si(R2)y IIa
- wherein:
- R1 is a hydrolysable group
- R2 is a functional organic group,
- R3 is an optional bridging linear or branched bivalent hydrocarbyl group, and
