The synthesis and opto-electronic properties of homopolymer and alternating copolymers of benzodithiophene with decyl phenylethynyl substituents are reported. The introduction of thiophene, bithiophene, and terthiophene spacers into alternating copolymers allowed the systematic variation of the spacing between the decyl substituents of benzodithiophene. The influence of spacing between the decyl substituents on the performance of bulk heterojunction solar cells with PCBM is investigated.
