Abstract
The invention provides a metallopolymer coordination network comprising one or more coinage or similar metals and a glyme or glyme-equivalent. The composition has an amorphous polymer network that is significantly stronger than previously reported supramolecular hydrogels synthesized without glyme. Glyme chain length and water content strongly influence the mechanical, electronic, and optical behavior of the network.
Claims21
A metallopolymer coordination network composition comprising a metallopolymer of Formula I:
- wherein
- M is a coinage metal;
- R—S is a sulfur-containing moiety wherein the ratio (R—S):M is 1:1;
- and
- Formula I is coordinated to one or more compounds of Formula A:
- wherein
- each A of Formula I is a Formula A moiety coordinated to M of Formula I;
- X is O or NR′ wherein R′ is H, alkyl, or aryl;
- R1 and R2 are each independently OH, alkoxy, or N(Ra)2 wherein each Ra is independently H or (C1-C8)alkyl;
- and
- n is 1, 2, 3, 4, or about 5 to about 50;
- wherein the metallopolymer is a polymer of coinage metal atoms linked together by the sulfur atoms of the sulfur-containing moieties, wherein one or more of the sulfur-containing moieties comprise carboxy or amino functional groups.

A metallopolymer composition of Formula II:
- wherein
- each M is copper, gold, silver, tin, nickel, aluminum, or titanium;
- each R is a sulfur-containing moiety comprising a carboxy or amino functional group wherein its sulfur atom is linked to M of the metallopolymer of Formula II;
- and
- each A is Formula A:
- wherein
- X is O or NR′ wherein one or more X is coordinated to M of Formula II;
- R′ is alkyl, methyl, ethyl, propyl, butyl, pentyl, cyclopropyl, cyclobutyl, or cyclopentyl;

- and
- n is 1, 2, 3, 4, or about 5 to about 50;
- wherein the ratio of the sulfur containing moiety and M is 1:1, the metallopolymer is a straight chain metallopolymer further comprising immobilized water, and the composition is electrically or ionically conductive.
