The present invention provides a composite comprising graphene, a conjugated porous organic polymer and a metalloprotein and to methods of making the composite. The invention also relates to articles (e.g. to an electrode) comprising the composite and to uses of the composite, e.g. in heterogeneous catalysis of oxygen reduction reactions, and in oxygen sensing.

The present disclosure relates to the surface modification of substrates using poly (2-oxazine)s. Specifically, the present disclosure provides the use one or more poly(2-alkyl-2-oxazine) or copolymers containing poly(2-alkyl-2-oxazine) in surface modification of a substrate. More in particular the present disclosure provides substrates having attached thereto, or associated therewith, one or more poly(2-alkyl-2-oxazine) or copolymers containing poly(2-alkyl-2-oxazine); wherein said alkyl is preferentially selected from the list comprising methyl and ethyl. The present disclosure also provides methods for preparing such substrates and uses thereof.

Macromolecules comprising triazoles and related compositions and methods are provided. In some embodiments, a macromolecule may comprise one or more repeat units including a triazole and a functionalizable pendant group. The macromolecule may also comprise one or more orthogonally addressable end groups. In some embodiments, one or more repeat units may be formed by a synthetic process that allows for precise control over stereochemistry, pendant functionality, and/or the spatial relationship (e.g., distance) between groups in the repeat unit(s). Such precise control over pendant group and repeat unit structure allows for the macromolecule functionality, stereochemistry, and spacing between groups (e.g., pendant groups) to be precisely controlled. Macromolecules described herein may be used for a wide variety of applications, including the delivery of active agents.

A polymer and a method of making the polymer from the below maleimide monomer having maleimidyl groups and the below furan monomer having furyl groups. The value n is a positive integer. The monomers are combined to form a composition, and at least one of the maleimidyl groups is reacted with at least one of the furyl groups to form a polymer comprising at least one crosslinking group show below. The polymer can be heated to remove the crosslinks.
