Abstract
There is provided an array of alkyl substituted silsesquioxane thin film precursors having a structure wherein alkyl groups are bonded to the silicon atoms of a silsesquioxane cage. The alkyl groups may be the same as, or different than the other alkyl groups. In a first aspect, the present invention provides a composition comprising a vaporized material having the formula [R—SiO1.5]x[H—SiO1.5]y, wherein x+y=n, n is an integer between 2 and 30, x is an integer between 1 and n and y is a whole number between 0 and n. R is a C1 to C100 alkyl group. Also provided are films made from these precursors and objects comprising these films.
