Narrow windows and large supercavities comprise the novel nanoporous coordination organometallic structure ℝPM-1, which has a two-fold interpenetrating 3D network containing unique open channels (see picture). ℝPM-1 exhibits a high sorption capacity for large hydrocarbons and superior size/shape selectivity for the photolysis of ortho-methyl dibenzyl ketone (o-MeDBK; 100 % cage effect). A completely reversible structural transformation takes place between ℝPM-1 and a nonporous 1D compound, which allows a full recovery of the o-MeDBK derived products (100 % mass balance).
