Abstract

Using recently reported robust porphyrinic metal-organic framework (RPM) materials, we have examined the systematic exchange of pillaring linkers/struts as a means of accessing new versions of these materials. Dipyridyl-porphyrin Zn(ii) (Zn-dipy) struts were successfully replaced by M2-dipy (M 2 = 2H(+), Al(iii), Sn(iv)), forming crystalline solid solutions of Zn(Zn1-xMx)-RPM in variable ratios. In addition, post-synthetic metallation was demonstrated using Zn2H-RPM, again with retention of crystallinity. We examined catalytic activity for an epoxide ring-opening reaction with a series of ZnM2-RPMs. The catalytic activity depends strongly on the identity of the metal ion present in the dipyridyl-porphyrin unit.
