Abstract
Provided are photodefinable compositions suitable for use in forming an optical waveguide. The compositions include a silsesquioxane polymer having polymerized units of the formula (RSiO) and (RSiO), wherein Rand Rare different and are substituted or unsubstituted organic side chain groups and are free of hydroxy groups, and two or more functional end groups, and a photoactive component. The solubility of the silsesquioxane polymer is altered upon exposure to actinic radiation such that the composition is developable in an aqueous developer solution. Also provided are methods of forming an optical waveguide with the inventive compositions, optical waveguides, and electronic devices including one or more optical waveguide.
