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&#x2014;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. Methods for making compounds of the general formula RMRRRare also disclosed.

Methods and compounds for making coatings, waveguides and other optical devices

A compound of the general formula: RRRMR, wherein R, Rand Rare independently an aryl, alkyl, alkenyl or alkynyl group, wherein at least one of R, Rand Ris fully or partially fluorinated, wherein M is selected from group 14 of the periodic table, and wherein Ris either an alkoxy group, OR, 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 RRRMRare also disclosed.

A method comprises reacting a compound of the general formula R1 MOR3 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 R1 MOR3 R2. A similar method of the invention comprises reacting a compound of the general formula R1 MOR3 X wherein m is an integer from 2 to 4, and n is an integer from 0 to 3 and is not greater than m; R1 is selected from alkyl, alkenyl, aryl, alkynyl or epoxy, and wherein R1 is nonfluorinated, or fully or partially fluorinated; OR3 is alkoxy; X is a halogen; 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 R2MR1 OR3 X . These compounds thus formed can be further reacted to attach an additional Rx group, 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.
