Patent ID: 8912535

Claim:
A bis(naphthalene diimide) compound or a mixture thereof having the structure: wherein a) hAr is a heteroaryl selected from: wherein i) “a” is an integer 1, 2, 3, or 4; ii) each X and X′ is independently selected from O, S, Se, or NR 6 , wherein R 6 is a C 1 -C 30 organic group independently selected from normal, branched, or cyclic alkyl, fluoroalkyl, aryl, heteroaryl, alkyl-aryl, and alkyl-heteroaryl groups optionally substituted with one or more fluoro, cyano, alkyl, alkoxy groups; iii) each Y, Y′, Y″ and Y′″ is independently selected from N, and CR 7 , where R 7 is hydrogen, fluoro, or a C 1 -C 30 organic group independently selected from cyano, normal, branched, or cyclic alkyl, perfluoroalkyl, alkoxy, perfluoroalkoxy, aryl, heteroaryl, alkyl-aryl, and alkyl-heteroaryl groups, optionally substituted with one or more fluoride, cyano, alkyl, alkoxy groups; iv) each Z and Z′ is independently selected from O, S, Se, C(R 8 ) 2 , Si(R 8 ) 2 , NR 8 , (CO), (CO) 2 or C═C(CN) 2 , wherein R 8 is a C 1 -C 30 organic group independently selected from normal, branched, or cyclic alkyl, perfluoroalkyl, aryl, heteroaryl, alkyl-aryl, and alkyl-heteroaryl groups, optionally substituted with one or more fluoro, cyano, alkyl, alkoxy groups; b) each R 1 and R 1′ is a C 1 -C 30 organic group independently selected from a normal, branched, or cyclic alkyl, aryl, heteroaryl, alkyl-aryl, or alkyl-heteroaryl group optionally substituted with one or more halide, cyano, alkyl, or alkoxy groups; c) R 2 , R 3 , and R 4 are independently selected from hydrogen, halide, or a C 1 -C 30 organic group independently selected from cyano, normal, branched, or cyclic alkyl, fluoroalkyl, aryl, heteroaryl, alkyl-aryl, acyl- and alkyl-heteroaryl groups, optionally substituted with one or more fluoro, cyano, alkyl, alkoxy groups.
