Preparation of Microporous Ga–Si–O Materials with Acidic Sites from a Gallium-Bridged Silsesquioxane

Abstract
Ga–Si–O materials with acidic sites and uniformly-controlled micropores have been prepared by the calcination of a new gallium-bridged silsesquioxane [HNEt3]+[Ga{(Me3Si)(c-C5H9)7Si7O12}2].
