Abstract

The invention relates to polymers and oligomers, methods of their synthesis, and electronic devices comprising them.

Claims (23)

1. A composition of matter comprising a polymer of the general structure:

wherein the R1 substituents are independently selected from the group consisting of hydrogen, alkyl groups, alkoxy groups, and aryl groups;

the R2 substituents are independently selected from the group consisting of hydrogen, alkyl groups, alkoxy groups, and aryl groups;

the R3 substituents are independently selected from the group consisting of hydrogen, alkyl groups, alkoxy groups, and aryl groups;

the R4 substituents are independently selected from the group consisting of hydrogen, alkyl groups, alkoxy groups, and aryl groups;

wherein bonds A and B may be either ortho or para with respect to the pyridyl nitrogen;

wherein bonds C and D may independently be either ortho, meta or para with respect one another;

wherein bonds E and F may be either ortho, meta or para with respect one another;

wherein bonds G and H may be either ortho, meta or para with respect one another;

wherein Y may be a moiety selected from the group consisting of —(CH 2 ) x —, —(CH 2 ) x O—, —O(CH 2 ) x — and —O(CH 2 ) x O— wherein x is an integer in the range of 1 to 15 inclusive;

wherein Z may be a moiety selected from the group consisting of —(CH 2 ) x —, —(CH 2 ) x O—, —O(CH 2 ) x — and —O(CH 2 ) x O— wherein x is an integer in the range of 1 to 15 inclusive; and

wherein n is an integer greater than 1.

2. A composition according to claim 1 wherein at least one R2 substituent is a methoxy group.

3. A composition according to claim 1 wherein at least two R2 substituents are methoxy groups.

4. A composition according to claim 1 wherein at least one R3 substituent is a methoxy group.

5. A composition according to claim 1 wherein at least two R3 substituents are methoxy groups.

6. A composition according to claim 1 wherein at least one R3 substituent is a methoxy group.

7. A composition according to claim 1 wherein at least two R3 substituents are methoxy groups.

8. A composition according to claim 1 wherein vinyl linkage A attaches at a position ortho to the pyridyl nitrogen.

9. A composition according to claim 1 wherein vinyl linkage B attaches at a position ortho to the pyridyl nitrogen.

10. A composition according to claim 1 wherein vinyl linkage A attaches at a position para to the pyridyl nitrogen.

11. A composition according to claim 1 wherein vinyl linkage B attaches at a position para to the pyridyl nitrogen.

12. A composition according to claim 1 wherein x is an integer in the range of 1 to 6 inclusive.
