Poly(2‐vinyl‐4,6‐diamino‐1,3,5‐triazine), (PVDT) with diaminotriazine residues is found to form not only intramolecular hydrogen bonds, but also three robust, complementary hydrogen bonds with nucleobases such as thymine and uracil. Taking advantage of the three complementary hydrogen bonds, molecular recognition of a nucleic acid base has been investigated in previous work. Over the past few years, the use of PVDT has been extended to the construction of gene delivery vectors and nonswellable, high‐strength hydrogels by copolymerization with a hydrophilic monomer and/or crosslinker. In particular, many fascinating properties, such as excellent mechanical properties, stimuli responsiveness, the shape memory effect, and biodegradability, have emerged in PVDT‐based hydrogels. In this article, the molecular recognition and self‐assembly of diaminotriazine are introduced first, and then a particular focus is placed on the development of PVDT‐based high performance hydrogels, especially their biorelated applications.

聚（乙烯基二氨基三嗪）：从分子识别到高强度水凝胶

具有二氨基三嗪残基的聚（2-乙烯基-4,6-二氨基-1,3,5-三嗪）（PVDT）不仅会形成分子内氢键，而且还会与胸腺嘧啶等核碱基形成三个牢固的互补氢键和尿嘧啶。利用三个互补氢键，在先前的工作中已经研究了核酸碱基的分子识别。在过去的几年中，通过与亲水性单体和/或交联剂共聚，PVDT的用途已扩展到构建基因传递载体和不可溶胀的高强度水凝胶。尤其是，在基于PVDT的水凝胶中出现了许多令人着迷的特性，例如出色的机械性能，刺激响应性，形状记忆效应和生物降解性。在本文中，
