example D
[0365] Example DiCN structures include structures according to Formula I:
[0366]
[0367] In compounds of formula I, optionally, Y is F, Cl, Br, alkoxy, alkyl or aryl. In compounds of formula I, optionally, n is an integer of 0-5. In the compound of formula I, optionally, X is C(CN) 2 , O, S, C(O) or SO 2 . Optionally, Ar is an aryl group such as phenyl, thienyl, thiazolyl and the like.
[0368] Examples of fused π systems include, but are not limited to: anthra[1,9-bc:5,10-b'c']dithiophenediyl (e.g., anthra[1,9-bc:5,10- b'c']dithiophene-1,6-diyl); 4,9-dihydro-s-indacene[1,2-b:5,6-b']dithiophenediyl (e.g., 4,9-dihydro-s-indacene[1,2-b:5,6-b′]dithiophene-2,7-diyl); unsubstituted and 5-substituted 5H- Dithieno[3,2-b:2′,3′-h]carbazolediyl (for example, 5-methyl-5H-dithieno[3,2-b:2′,3′-h] carbazole-2,8-diyl); unsubstituted and 4-substituted 4H-dithieno[3,2-b:2′,3′-d]pyrrolediyl (e.g., 4-methyl Base-4H-dithieno[3,2-b:2′,3′-d]pyrrole-2,6-diyl or 4-(4-methylphenyl)-4H-di...
