Abstract
“Black” photoactive materials that comprise synthetic eumelanin polymers are provided, as are methods of making and using the polymers. The synthetic eumelanin polymers are made from the plant oil vanillin, and exhibit defined structural and chemical characteristics (e.g. homogeneity, solubility, etc.) that make them suitable for use in devices that require photoactive materials, such as solar cells.
Claims3
A polymer of Formula III
- where R1, R2, R3 and R4 vary independently and may be the same or different, and can be H;
- substituted or unsubstituted alkylester;
- substituted or unsubstituted alkoxy:
- P is H or CH3;
