A method of forming a silsesquioxane/Q/siloxane polymer or oligomer system used to form coatings or monoliths, includes the step of mixing silsesquioxane, siloxane and alkoxysilane components having structures as presented below in ratios as presented below with a soluble F

catalyst and water in a suitable solvent so that on stirring at temperatures of −20° to approximately 100° C. all of the components dissolve producing a solution. A soluble oligomer is formed in equilibribum with single molecules with specific structures including [RSiO
