    Abstract: A method of forming a molecular complex. The method proceeds by reacting 5-chloro-2,1,3-benzothiadiazole with N-bromosuccinimide to produce 4,7-dibromo-5-chlorobenzo[c][1,2,5]thiadiazole. 4,7-dibromo-5-chlorobenzo[c][1,2,5]thiadiazole is then reacted with trimethyl[4-(2-octyldodecyl)thiophen-2-yl]stannane to produce 5-chloro-4,7-bis(4-(2-octyldodecyl)thiophen-2-yl)benzo[c][1,2,5]thiadiazole. 4, 7-bis(5-bromo-4-(2-octyldodecyl)thiophen-2-yl)-5-chlorobenzo[c][1,2,5]thiadiazole is subsequently synthesized from 5-chloro-4,7-bis(4-(2-octyldodecyl)thiophen-2-yl)benzo[c][1,2,5]thiadiazole. 4,7-bis(5-bromo-4-(2-octyldodecyl)thiophen-2-yl)-5-chlorobenzo[c][1,2,5]thiadiazole with tributyl(thiophen-2-yl)stannane is then reacted to produce 4-bromo-5,6-difluoro-7-(thiophen-2-yl)benzo[c][1,2,5]thiadiazole. This is followed by reacting 4,7-dibromo-5-chloro-2,1,3-benzothiadiazole with tributyl(thiophen-2-yl)stannane to produce 4-bromo-5-chloro-7-(thiophen-2-yl)benzo[c][1,2,5]thiadiazole. trimethyl[4-(2-octyldodecyl)thiophen-2-yl]stannane is then reacted with and 4-bromo-5-chloro-7-(thiophen-2-yl)benzo[c][1,2,5]thiadiazole to produce 5-chloro-4-(4-(2-octyldodecyl)thiophen-2-yl)-7-(thiophen-2-yl)benzo[c][1,2,5]thiadiazole. 5-chloro-4-(4-(2-octyldodecyl)thiophen-2-yl)-7-(thiophen-2-yl)benzo[c][1,2,5]thiadiazole is then reacted with N-bromosuccinimide to produce the co-monomer 4-(5-bromo-4-(2-octyldodecyl)thiophen-2-yl)-7-(5-bromothiophen-2-yl)-5-chlorobenzo[c][1,2,5]thiadiazole. A group can then be coupled to 4-(5-bromo-4-(2-octyldodecyl)thiophen-2-yl)-7-(5-bromothiophen-2-yl)-5-chlorobenzo[c][1,2,5]thiadiazole to produce a molecular complex.

    Abstract: A comonomer comprising:




    wherein W is selected from the group consisting of: S, Se, O, and N-Q; and Q is selected from the group consisting of: a straight-chain or branched carbyl, silyl, or hydrocarbyl, a branched or cyclic alkyl with 1 to 30 atoms, a fused substituted aromatic ring, and a fused unsubstituted aromatic ring. In this comonomer, A and B are independently selected from the group consisting of: H, Br, an aryl group, and a heteroaryl group.
