Abstract
The poor water stability of most porous coordination
polymers (PCPs) or metal-organic frameworks (MOFs) is widely
recognised as a barrier hampering their practical applications.
Herein, a facile and scalable route to prepare metal-containing
polymers with a good stability in boiling water (100oC, 24 h) and air
(up to 390oC) is presented. The bifunctional 1-vinylimidazole (VIm)
with both a coordinating site and a polymerizable organic group is
introduced as the building block. This core strategy includes the
synthesis of a rigid monomer with four VIm branches via a
coordination process at room temperature, followed by a radical
polymerization. Here we call this material Coordination-supported
Imidazolate Networks (CINs). Interestingly, CINs are composed of
rich mesopores from 2 to 15 nm, as characterized by low-energy (60
kV) STEM-HAADF images. Especially, the stable CINs illustrate a
high turnover frequency (TOF) of 779 h-1 in the catalytic oxidation of
phenol with H2O as the green solvent.
