Synthesis of a new bis-porphyrinic system coupled with biphenyl-20-crown-6 as an allosteric spacer, 1, is described; the incorporated rotatable biphenyl unit is capable of regulating the porphyrin center-to-center distance by an encapsulated metal ion in the crown-strapped cavity, so that the system displayed a potentially heterotropic allostery at the binding stage with a certain stereogenic α,ω-diamine
描述了一种新的双卟啉系统的合成,该系统结合了联苯20冠6作为变构间隔基1。内置的可旋转联苯单元能够通过冠状束缚腔中的包封金属离子调节卟啉中心距,从而使该系统在结合阶段具有一定的立体定向α,ω-二胺客人,2。
