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.
