Molecular and extended framework materials, from proteins to catenanes and metal-organic frameworks, can assume knotted configurations in their bonding networks (the chemical graph). Indeed, knot theory and structural chemistry have remained closely allied, due to those connections. Here we introduce a new class of graph entanglement: "ravels". These ravels-often chiral-tangle a graph without the presence of knots. Just as knots lie within cycles in the graph, ravels lie in the vicinity of a...[Show more]
