Application

Chlorotriisobutylsilane can be used as an intermediate in the synthesis of:
  • Silicon (IV) phthalocyanines, which are used as photosensitizers for the photodynamic inactivation of bacteria.
  • Poly(4-alkylthiazole) polymers exhibiting optical and electronic properties.
  • Bis(trialkylsilyl oxide) based silicon phthalocyanines applicable as ternary additives in organic photovoltaics.
