ABSTRACT:
A compound of the general formula R1R2MR4R5is disclosed wherein R1and R2are independently an aryl, alkyl, alkenyl, epoxy or alkynyl group, wherein at least one of R1and R2is fully or partially fluorinated, wherein M is selected from group 14 of the periodic table, wherein R4and R5are independently an alkoxy group, OR3, or a halogen group, X, except where M is Si, R4and R5are both ethoxy groups or both chlorine groups, and R1and R2are perfluorinated groups. This compound formed can be further reacted to attach an additional organic R group, and/or hydrolyzed, alone or with one or more similar compounds, to form a material having a molecular weight of from 500 to 10,000, which material can be deposited on various substrates as a coating or deposited and patterned for a waveguide or other optical device components. Methods for making compounds of the general formula R1MR4R5R6are also disclosed.
