Patent ID: 7709465

Claim:
A compound having formula FX1: wherein: n is 0 or an integer from 1-6, inclusive; Aryl rings A, B and C, independently of one another, are selected from the group consisting of or optionally substituted phenyl rings; X A , X B , X C represent one or more hydrogens or non-hydrogen substituents independently selected from the group consisting of halogens, hydroxides, alkyl, alkenyl, alkynyl, alkoxide, thiol, thioalkoxide, ether, thioether, nitro, cyano, isocyano, cyanato, isocyanato, thiocyano, isothiocyano, amine (—N(R′) 2 ), R′—CO—, R′O—CO—, (R′) 2 N—CO—, R′O—COO—, (R′) 2 N—COO—, (R′) 2 N—CONR′, R′SO 2 — and R′ 2 NSO 2 — groups, wherein carbon atoms of these substituent groups are optionally substituted with one or more halogens, hydroxides, thiols, nitro groups, cyano groups, isocyano groups, cyanato groups, isocyanato groups, thiocyanato groups, or isothiocyano groups; OR 2 is optionally replaced with Y which is a halogen; and R 1 and R 2 , independently of one another, are selected from the group consisting of alkenyl and alkynyl groups which are optionally substituted with one or more halogens, hydroxides, alkoxide, thiol, thioalkoxide, ether, thioether, amine (—N(R′) 2 ), nitro, cyano, isocyano, cyanato, isocyanato, thiocyano, isothiocyano, R′—CO—, R′O—CO—, (R′) 2 N—CO—, R′O—COO—, (R′) 2 N—COO—, (R′) 2 N—CONR′, R′SO 2 —, or R′ 2 NSO 2 — group; where each R′, independent of other R′ in the molecule, are selected from the group consisting of hydrogen, alkyl, alkenyl, alkynyl, and aryl, optionally substituted with one or more halogen, hydroxide, alkyl, alkenyl, alkynyl, alkoxide, thiol, thioalkoxide, ether, thioether, nitro, cyano, isocyano, cyanato, isocyanato, thiocyano, isothiocyano, amine (—N(R′) 2 ), R″CO—, (R″)O—CO—, (R″) 2 N—CO—, R″)O—COO—, (R″) 2 N—COO—, (R″) 2 N—CONR″, R″SO 2 —, or R″ 2 NSO 2 —groups; and where each R″, independently of other R″ in the molecule, are selected from the group consisting of hydrogen, alkyl, alkenyl, alkynyl, and aryl groups optionally substituted with one or more halogen, hydroxide, thiol, nitro, cyano, isocyano, cyanato, isocyanato, thiocyanato, or isothiocyano groups.
