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.
本文提供了包含三唑的大分子及相关组合物和方法。在某些实施方案中,大分子可包含一个或多个重复单元,其中包括三唑和可官能化的悬垂基团。大分子还可包括一个或多个可正交寻址的末端基团。在某些实施方案中,一个或多个重复单元可通过合成工艺形成,该工艺可精确控制立体化学、悬垂官能团和/或重复单元中基团间的空间关系(如距离)。通过这种对悬垂基团和重复单元结构的精确控制,可以精确控制大分子的功能性、立体化学和基团(如悬垂基团)之间的间距。本文所述的大分子可用于多种应用,包括活性剂的输送。
