ABSTRACT:
A compound of the general formula: R1R2R4MR5, wherein R1, R2and R4are independently an aryl, alkyl, alkenyl or alkynyl group, wherein at least one of R1, R2and R4is fully or partially fluorinated, wherein M is selected from group 14 of the periodic table, and wherein R5is either an alkoxy group, OR3, or a halogen group, X. This compound formed can be further reacted to attach an additional organic R group, and/or hydrolyzed with one or more similar compounds (preferably having one or two R groups bound to M), 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 and using compounds of the general formula R1R2R4MR5are also disclosed.
