  • Patent number: 7161019
    Abstract: A compound of the general formula R1MR4R5R6 is provided where R1 is a partially or fully fluorinated aryl, alkyl, alkenyl or alkynyl group, wherein M is selected from group 14 of the periodic table, wherein R4, R5 and R6 are independently an alkoxy group OR3 or a halogen group X—except, a) where R4, R5 and R6 are each ethoxy, M is Si and R1 is perfluorinated phenyl or perfluorinated vinyl; b) where R4 is ethoxy, R5 and R6 are chlorine, M is Si, and R1 is perfluorinated phenyl; or c) where R4, R5 and R6 are chlorine, M is Si, and R1 is 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.

  • Patent number: 7098346
    Abstract: A compound of the general formula: R1R2R4MR5, wherein R1, R2 and R4 are independently an aryl, alkyl, alkenyl or alkynyl group, wherein at least one of R1, R2 and R4 is fully or partially fluorinated, wherein M is selected from group 14 of the periodic table, and wherein R5 is 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 R1R2R4MR5 are also disclosed.

  • Patent number: 6831189
    Abstract: A method comprises reacting a compound of the general formula R14-mMOR3m wherein m is an integer from 2 to 4, R1 is selected from alkyl, alkenyl, aryl, alkynyl or epoxy, and wherein R1 is nonfluorinated, or fully or partially fluorinated; OR3 is alkoxy; and M is an element selected from group 14 of the periodic table; with a compound of the general formula R2M1 wherein R2 is selected from alkyl, alkenyl, aryl, alkynyl or epoxy, and wherein R2 is at least partially fluorinated; and M1 is an element from group I of the periodic table; so as to make a compound of the general formula R14-mMOR3m-1R2.
