- 論文の詳細を見る
We have developed organic-inorganic silicophosphate and silicophenylphosphite hybrid materials by means of alcohol condensation between organically modified alkoxysilane and anhydrous phosphoric or phosphonic acid under a solventless, catalyst-free, low-temperature, one-pot condition. The hybrid exhibits a low-melting property and is chemically more durable than that prepared by using a nonaqueous acid-base reaction between anhydrous phosphoric acid and organically modified chlorosilane. 29Si and 31P NMR analyses have shown that the alcohol condensation yield was around 80%. Quantum chemical calculations have also performed in order to clarify the chemical durability improvement of the hybrids.
