The present disclosure provides novel poly(phenylene ethynylene) (PPE) compounds, methods for synthesizing these compounds, and materials and substances incorporating these compounds. The various PPEs show antibacterial, antiviral and antifungal activity.
Claims17
A material incorporating a poly(phenylene ethynylene), the poly(phenylene ethynylene) having the structure:
- wherein
- the poly(phenylene ethynylene) is grafted to the material by chemisorption or wherein the polymer is attached to the material by physisorption;
- n is selected from the group consisting of whole numbers between 5 and 200;
- A is C2C6H2;
- B is selected from the group consisting of C2C6H2 and C2C4S;
- C=is either C6H4 or not present;
- X is selected from the group consisting of:
- [C2C6H4]2COOCH2CH3 and [C2C4H2S][C2C6H4]COOCH2CH3;
- Y is selected from the group consisting of:
- COOCH2CH3;
- ZA is selected from the group consisting of O(CH2)k(C6H12N2)C6H132+, O(CH2)kSO3−, and O(CH2)kN(CH3)3+;
- where k is selected from the group consisting of the whole number between 1 and 10;
- ZB is H;
- if ZA is O(CH2)k(C6H12N2)C6H132+, then A=C2C6H2, C is C6H4, Y is COOCH2CH3, and X is [C2C6H4]2COOCH2CH3;
- and
- if ZA is O(CH2)kN(CH3)3+ and C is present, then Y=COOCH2CH3 and X is selected from the group consisting of [C2C6H4]2COOCH2CH3 and [C2C4H2S][C2C6H4]COOCH2CH3, wherein
- if B=C2C6H2, then X is [C2C6H4]2COOCH2CH3, and
- if B=C2C4S, then X is [C2C4H2S][C2C6H4]COOCH2CH3.
