Abstract
Disclosed is a cyclic peptide polymer having the below structure. Each R1 and each R2 is an organic group. Each R3 is a covalent bond or methylene. The values m and n are nonnegative integers having a sum of at least 1. Each X is —NH—CO— or —CO—N—. The value p is an integer greater than 1. The cyclic peptide polymer may be made by providing a cyclic peptide having two side chains having terminal amino groups or carboxylic acid groups, and reacting the amino groups with an azobenzene or the carboxylic acid groups with an azodianiline.
Claims6
The cyclic peptide polymer of claim 1, wherein the cyclic peptide polymer has the structure:
The cyclic peptide polymer of claim 1, wherein the cyclic peptide polymer has the structure:
A method comprising:
- providing the cyclic peptide polymer of claim 1;
- wherein the —N≡N— bond is in either a cis state or a trans state;
- exposing the cyclic peptide polymer to light that converts the cis state to the trans state or the trans state to the cis state.
A method comprising:
- providing a cyclic peptide monomer comprising two side chains having terminal amino groups or carboxylic acid groups;
- reacting the amino groups with an azobenzene or the carboxylic acid groups with an azodianiline to form a cyclic peptide polymer.
