Patent ID: 7550207

Claim:
A polymer represented by Formula 1: wherein Ar is selected from the group consisting of a substituted or unsubstituted arylene group of C6-C30 and a substituted or unsubstituted heteroarylene group of C2-C30; R 1 through R 14 are each independently selected from the group consisting of hydrogen, a substituted or unsubstituted alkyl group of C1-C30, a substituted or unsubstituted cycloalkyl group of C3-C30, a substituted or unsubstituted aryl group of C6-C30, a substituted or unsubstituted arylalkyl group of C6-C30, a substituted or unsubstituted trialkylsilyl group of C3-C30, a substituted or unsubstituted alkoxy group of C1-C30, a substituted or unsubstituted aryloxy group of C6-C30, a substituted or unsubstituted heteroaryl group of C5-C30, a substituted or unsubstituted heteroarylalkyl group of C5-C30, a substituted or unsubstituted heteroaryloxy group of C5-C30, and a substituted or unsubstituted heterocycloalkyl group of C5-C30; X 1 and X 2 are each independently S, NR 15 , Si(R 16 R 17 ), or PR 18 where R 15 , R 16 , R 17 , and R 18 are each independently selected from the group consisting of hydrogen, a substituted or unsubstituted alkyl group of C1-C30, a substituted or unsubstituted cycloalkyl group of C3-C30, a substituted or unsubstituted aryl group of C6-C30, a substituted or unsubstituted arylalkyl group of C6-C30, a substituted or unsubstituted trialkylsilyl group of C3-C30, a substituted or unsubstituted alkoxy group of C1-C30, a substituted or unsubstituted aryloxy group of C6-C30, a substituted or unsubstituted heteroaryl group of C5-C30, a substituted or unsubstituted heteroarylalkyl group of C5-C30, a substituted or unsubstituted heteroaryloxy group of C5-C30, and a substituted or unsubstituted heterocycloalkyl group of C5-C30; M is C, Ge, Si, or Sn; and n is a real number from 0 to 0.99.
