Abstract

Porphyrin polymers of Structure 1, where n is an integer (e.g., 1, 2, 3, 4, 5, or greater) are synthesized by the method shown in FIGS. 2 A and 2 B. The porphyrin polymers of Structure 1 are soluble in organic solvents such as 2-MeTHF and the like, and can be synthesized in bulk (i.e., in processes other than electropolymerization). These porphyrin polymers have long excited state lifetimes, making the material suitable as an organic semiconductor for organic electronic devices including transistors and memories, as well as solar cells, sensors, light-emitting devices, and other opto-electronic devices.

Claims (16)

1. A polymer having the structure:

where n is an integer.

2. The polymer of claim 1 , wherein n is 1 to 5.

3. The polymer of claim 1 , wherein n is greater than 5.

4. A device comprising the polymer of claim 1 .

5. The device of claim 4 , wherein the device is an electronic device.

6. The device of claim 4 , wherein the device is an opto-electronic device.

7. The device of claim 4 , wherein the device is a photovoltaic device.

8. A method of synthesizing a porphyrin polymer having Structure 1:

wherein n is an integer, and the porphyrin polymer having Structure 1 is synthesized in bulk.

9. The method of claim 8 , wherein synthesizing the porphyrin polymer having Structure 1 occurs in the absence of electropolymerization.

10. The method of claim 8 , wherein synthesizing the porphyrin polymer having Structure 1 occurs via a brominated porphyrin monomer.

11. The method of claim 10 , wherein synthesizing the porphyrin polymer having Structure 1 occurs via a brominated porphyrin monomer having Structure 2:

12. The method of claim 11 , wherein the brominated porphyrin monomer having Structure 2 is synthesized via a porphyrin monomer having Structure B:

13. The method of claim 12 , wherein the porphyrin monomer having Structure B is synthesized via a porphyrin monomer having structure A:

14. The method of claim 8 , wherein the porphyrin polymer having Structure 1 is free of defects having Structure 6:
