We introduce the synthesis of photosensitive tetrazole monomers via Passerini multicomponent reactions (MCRs). We exploit the MCR's tolerance toward various functional groups under mild, catalyst-free conditions in a one-pot reaction setup to generate tetrazole-containing monomers featuring a methacrylic moiety, which enables their subsequent reversible addition-fragmentation chain transfer (RAFT) polymerization. By employing tetrazoles with either a 4-methoxy phenyl or a pyrene substituent, further modifications of the polymers in a wavelength-orthogonal, self-reporting fashion upon irradiation with either UV or visible light become possible.
我们介绍了通过Passerini多组分反应（MCRs）合成光敏四唑单体的方法。我们利用MCR在温和、无催化剂条件下对各种官能团的耐受性，在一锅反应装置中生成含有甲基丙烯酸部分的含四唑单体，这使得它们随后能够进行可逆加成-断裂链转移（RAFT）聚合。通过使用带有4-甲氧基苯基或芘取代基的四唑，在用紫外线或可见光照射时，聚合物能够以波长正交、自报告的方式进行进一步修饰。
