Patent ID: 7524567

Claim:
A spirofluorene-based polymer having Formula 3: wherein each of R 1 to R 4 is a mono-substituted or multi-substituted substituent, and is independently selected from the group consisting of a hydrogen, a hydroxy group, an amino group, a substituted or unsubstituted C 1-30 alkylamino group, a substituted or unsubstituted C 6-30 arylamino group, a substituted or unsubstituted C 2-30 heteroarylamino group, a cyano group, a halogen atom, a substituted or unsubstituted C 1-30 alkyl group, a substituted or unsubstituted C 3-30 cycloalkyl group, a substituted or unsubstituted C 1-30 alkoxy group, a substituted or unsubstituted C 6-30 aryl group, a substituted or unsubstituted C 6-30 aryloxy group, a substituted or unsubstituted C 6-30 aryl alkyl group, a substituted or unsubstituted C 2-30 heteroaryl group and a substituted or unsubstituted C 2-30 heterocyclic group, at least one of R 1 and R 2 , and R 3 and R 4 may be linked to each other to form a saturated or unsaturated ring, Ec 1 and Ec 2 are independently selected from the group consisting of the moieties having Formulae 2a through 2w: wherein R 5 to R 10 are mono-substituted or multi-substituted functional groups and are independently selected from the group consisting of at least one F or —(CF 2 ) n CF 3 where n=an integer of 1 to 12, a substituted or unsubstituted C 6-30 aryl group having at least one F or —(CF 2 ) n CF 3 where n=an integer of 1 to 12, a substituted or unsubstituted C 2-30 heteroaryl group having at least one F or —(CF 2 ) n CF 3 where n=an integer of 1 to 12, a substituted or unsubstituted C 2-30 heterocyclic group having at least one F or —(CF 2 ) n CF 3 where n=an integer of 1 to 12, a substituted or unsubstituted C 3-30 cycloalkyl group having at least one F or —(CF 2 ) n CF 3 where n=an integer of 1 to 12, and a substituted or unsubstituted C 6-30 fused aryl group having at least one F or —(CF 2 ) n CF 3 where n=an integer of 1 to 12; Ar is selected from the group consisting of a substituted or unsubstituted C 6-30 arylene group, a substituted or unsubstituted C 2-30 heteroarylene group, and a substituted or unsubstituted C 2-30 heterocyclic group; x is a real number of 1 or 0.01 to 0.99; y is a real number of 0 or 0.01 to 0.99; and z represents the degree of polymerization and is a real number of 10 to 150.
