ABSTRACT:
The invention is directed to aromatic vinyl sulfide compounds of general formula A(—S—CH═CH2)z, wherein z is in the range of 1–4 and A represents highly halogenated and highly halogenated-deuterated phenyl, biphenyl and naphthalene compounds; highly halogenated and highly halogenated-deuterated biphenyl ethers and thioethers; and highly halogenated and highly halogenated-deuterated unsaturated 5- and 6-member heterocyclic ring systems containing carbon and at least one heteroatom selected from the group consisting of nitrogen, oxygen and sulfur. The aromatic vinyl sulfide compounds of the invention can be used to prepare elements and devices suitable for use in optical communications.
