… While an increasing number of homochiral MOFs are being reported, 6 only a limited
number of these materials are both porous and robust. In this Communication we make use
of a novel chiral ligand to construct a robust homochiral porous MOF with the formula [Ag 4 (L(S))
3 (NO 3 ) 4 ]·x(Guest) 1·x(Guest) (where L(S) is 1,4-benzylidene-bis(S,S)-4-yl-3,5-bis(1-hydroxyethyl)-1,2,4-triazole
(Fig. 1(a)). The homochiral pore structure of 1 makes it an excellent candidate for
enantioselective applications. … In summary we have reported a robust nanoporous …
Assembly of the novel homochiral ligand L(S) (where L(S) is 1,4-benzylidene-bis(S,S)-4-yl-3,5-bis(1-hydroxyethyl)-1,2,4-triazole) and AgNO3 generates a robust, porous, chiral and cationic framework that exhibits reversible guest adsorption.
