Abstract
A compound of the general formula RMRRRis provided where Ris a partially or fully fluorinated aryl, alkyl, alkenyl or alkynyl group, wherein M is selected from group 14 of the periodic table, wherein R, Rand Rare independently an alkoxy group ORor a halogen group X—except, a) where R, Rand Rare each ethoxy, M is Si and Ris perfluorinated phenyl or perfluorinated vinyl; b) where Ris ethoxy, Rand Rare chlorine, M is Si, and Ris perfluorinated phenyl; or c) where R, Rand Rare chlorine, M is Si, and Ris perfluorinated phenyl, perfluorinated methyl or perfluorinated vinyl. 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.
