合成了一种高效的硫醇-迈克尔加成反应的可见光敏感光碱发生器，并对其进行了评价。这种高活性催化剂是通过用香豆素衍生物的可见光响应基团保护强碱（四甲基胍，TMG）而设计的。香豆素偶联的TMG在可见光照射下对硫醇-迈克尔反应（包括硫醇-迈克尔加成聚合）的起始表现出非凡的催化活性，导致硫醇和乙烯基官能团的化学计量反应。由于它的特点，这种可见光光碱产生器可以在巯基-迈克尔聚合中形成均匀的网络，并且也有潜力用于其他可见光诱导的、碱催化的巯基点击过程，如巯基-异辛酸酯和巯基-环氧树脂形成网络的反应。
An efficient visible-light-sensitive photobase generator for thiol-Michael addition reactions was synthesized and evaluated. This highly reactive catalyst was designed by protecting a strong base (tetramethyl guanidine, TMG) with a visible-light-responsive group which was a coumarin derivative. The coumarin-coupled TMG was shown to exhibit extraordinary catalytic activity toward initiation of the thiol-Michael reaction, including thiol-Michael addition-based polymerization, upon visible-light irradiation, leading to a stoichiometric reaction of both thiol and vinyl functional groups. Owing to its features, this visible-light photobase generator enables homogeneous network formation in thiol-Michael polymerizations and also has the potential to be exploited in other visible-light-induced, base-catalyzed thiol-click processes such as thiol-isocynate and thiol-epoxy network-forming reactions.
