The application of triphenylsilanol in polymer synthesis is mainly reflected in the following aspects:

As a pharmaceutical intermediate: triphenylsilanol is an important chemical substance with a molecular formula of C18H16OSi. Due to its unique chemical properties, it is widely used in the synthesis of pharmaceutical intermediates. Pharmaceutical intermediates are key raw materials for the synthesis of drugs, and various drugs with specific efficacy can be synthesized through different chemical reactions.

Functionalization in polymer synthesis: The hydroxyl group (OH) on triphenylsilanol gives it the ability to react with other chemical substances. This reactivity allows triphenylsilanol to be used as a functionalizing agent in polymer synthesis, used to introduce specific functional groups or structures into the polymer chain, thereby changing the properties of the polymer or giving it new functions.

Improving the physical and mechanical properties of silicone rubber: In the preparation and performance research of silicone materials for LED packaging, triphenylsilanol (or its analogs) can react with trifunctional silicone monomers through specific chemical reactions, such as the "top angle-capping" method, to generate phenylvinyl POSS with reactive vinyl groups. This phenylvinyl POSS can be introduced into the addition type liquid silicone rubber system, and the phenylvinyl POSS/silicone rubber organic-inorganic hybrid material can be prepared by the hydrosilylation reaction. This hybrid material shows excellent performance in terms of structure, morphology, thermal stability, melting temperature, mechanical properties and hardness.

In summary, the application of triphenylsilanol in polymer synthesis mainly includes as a pharmaceutical intermediate, a functional reagent in polymer synthesis, and improving the physical and mechanical properties of silicone rubber. Its unique chemical properties and reactivity make it one of the indispensable and important raw materials in the field of polymer synthesis.
