Synthesizing polymers with precise sequence structures is of great significance but is still a great challenge in polymer science. The exploration of alkyne-based polymerizations recently has attracted considerable attention due to their great potential to construct polymers with diverse structures and versatile functions, especially those with precise sequence structures. In this review, we summarized recent advances in the preparation of sequence-controlled polymers by alkyne-base polymerizations. Representative examples of each method were selected to illustrate the essential construction principles and implementation approaches, which are expected to provide guidance for the development of sequence-controlled polymers. In addition, we also systematically introduce the diverse and appealing properties and applications of the obtained sequence-controlled polymers, hoping to promote the development of polymeric materials with more superior and innovative properties and applications.
