Structure, synthesis, and applications for oligo phenylene ethynylenes (OPEs)

A material incorporating an oligo-(phenylene ethynylene), wherein the oligo-(phenylene ethynylene) is grafted thereto by chemisorption or wherein the positively charged polymer attaches to a negatively charged surface by physisorption, wherein the oligo-(phenylene ethynylene) has the structure:

• wherein:
• n is selected from the group consisting of 1, 2, 3 and 4;
• A is selected from the group consisting of C2C6H2 and C2C4S;
• B=C2C6H2;
• C=is either C6H4 or not present;
• X is selected from the group consisting of:
• COOCH2CH3, O(CH2)kN(CH3)3+, O(CH2)kSO3−, and O(CH2)k(C6H12N2)C6H13;
• Y is selected from the group consisting of:
• COOCH2CH3, O(CH2)kN(CH3)3+, O(CH2)kSO3−, C6H2(OCH3)3, and O(CH2)k(C6H12N2)C6H132+;
• k is selected from the group of whole numbers from 1 to 10;
• ZA is selected from the group consisting of H and O(CH2)j(C6H12N2)C6H132+;
• where j is selected from the group of whole numbers from 1 to 10;
• and
• ZB=H;
• wherein:
• if X=COOCH2CH3 and Y=COOCH2CH3, then A=B=C2C6H2, C is C6H4, and ZA is O(CH2)k(C5H12N2)C6H132+;
• if ZA is H, A is C2C6H2, X=O(CH2)kN(CH3)3+, and C=C6H4, then Y is selected from the group consisting of COOCH2CH3, O(CH2)kSO3−, C6H2(OCH3)3, and O(CH2)k(C6H12N2)C6H132+;
• if ZA is H, A is C2C6H2, X=O(CH2)kN(CH3)3+, C=C6H4, and B=C2C6H2, then k is selected from the group consisting of 1, 2, 4, 5, 6, 7, 8, 9, and 10;
• if ZA is H, A is C2C6H2, X=O(CH2)kN(CH3)3+, and C is not present, then Y=C6H2(OCH3)3;
• if ZA is H, A is C2C6H2 and X=O(CH2)kSO3−, then C=C6H4 and Y=O(CH2)kSO3−;
• if ZA is H, A is C2C6H2, and X=O(CH2)k(C5H12N2)C6H132+, then C=C6H4 and Y=O(CH2)k(C6H12N2)C6H132+;
• if A is C2C4S, then C=C6H4 and X is selected from the group consisting of O(CH2)kN(CH3)3+ and O(CH2)k(C6H12N2)C6H132+;
• if X is O(CH2)k(C6H12N2)C6H132+, then Y=O(CH2)k(C6H12N2)C6H132+;
• wherein both the oligo-(phenylene ethynylene) and the material incorporating the same have biocidal, antiviral, and antifungal properties.
