Provided is a novel aromatic ether capped naphthalocyanine compound containing a central hetero atom having a siloxy group substituent off of said hetero atom, with said siloxy substituent having the formula -OSiR1R2-ZAr wherein R1 and R2 can be the same or different, and can be alkyl having from 1 to about 18 carbons; aryl having from 6 to 10 carbons; cycloalkyl having at least 4 carbons or alkoxy having at least 3 carbons, Z is O or S, and Ar is an aromatic moiety. Also provided is a process for preparing a naphthalocyanine compound containing a central hetero atom having a siloxy group substituent off of said hetero atom, with said siloxy group containing a terminal ether function, which process comprises reacting in the presence of a nucleophile in a moisture free environment (i) a naphthalocyanine dihydroxy compound, (ii) a compound of the formula SiR1R2L2, wherein R1 and R2 can be the same or different and can be alkyl having from 1 to about 18 carbons; aryl having from 6 to 10 carbons; cycloalkyl having at least 4 carbons or alkoxy having at least 3 carbons, and L is a halogen, and (iii) an ether capping group compound, wherein the ether capping group compound is added to the reaction medium under moisture free conditions.
