Patent ID: 8071760

Claim:
A compound having the structure: wherein: the R 1 -R 4 groups are the same or different, and each is selected from the group consisting of hydrogen, phenyl, hydroxyphenyl, (C 2 B 9 H 11 )phenyl, (C 2 B 10 H 11 )phenyl, pyridyl, substituted pyridyl, and metallobisdicarboillides; the Groups R 5 , R 6 , R 7 and R 8 are the same or different, and are selected from the group consisting of hydrogen, metal atoms, and (CH 2 CH 2 O) 2 [Co(C 2 B 9 H 11 ) 2 ]; and the two Y 1 groups are the same, the two Y 2 groups are the same, the two Y 3 groups are the same, and the two Y 4 groups are the same; wherein the several groups Y 1 , Y 2 , Y 3 and Y 4 may be the same or different from one another; and wherein the groups Y 1 , Y 2 , Y 3 and Y 4 are each selected from the group consisting of hydrogen, â€”CHâ•CHâ€”, methyl, ethyl, propyl, isopropyl, and butyl; and wherein if, the two Y n groups are â€”CHâ•CHâ€”, wherein n is 1, 2, 3 or 4, then those two Y n groups are bonded together to form the group â€”CHâ•CHâ€”CHâ•CHâ€”, so that the compound thereby contains a fused benzene ring at the Y n positions; and at least one of Y 1 , Y 2 , Y 3 , Y 4 , R 1 , R 2 , R 3 , and R 4 is not hydrogen.
