Description
In this study, we examined the reduction in crystal size of the porous coordination polymers (PCPs) {Sr4(H2O)9][4Ru]2·9H2O]} (Sr2[4Ru]) and [Mg(H2O)6]{[Mg2(H2O)3[4Ru]·4H2O} (Mg2[4Ru]) composed of a luminescent metalloligand [Ru(4,4′-dcbpy)]4–([4Ru]; 4,4′-dcbpy = 4,4′-dicarboxy-2,2′-bipyridine) using a coordination modulation method. Scanning electron microscopy measurements clearly show that the sizes of crystals of Sr2[4Ru] and Mg2[4Ru] were successfully reduced to the mesoscale (about 500 nm width and 10 nm thickness for Sr2[4Ru] (abbreviated as m-Sr2[4Ru]) and about 1 μm width and 30 nm thickness for Mg2[4Ru] (abbreviated as m-Mg2[4Ru])) using lauric acid as a coordination modulator. Interestingly, the nanocrystals of m-Sr2[4Ru] formed flower-like aggregates with diameters of 1 μm, whereas flower-like aggregates were not formed in m-Mg2[4Ru]. Water vapor adsorption isotherms of these nanocrystals suggest that the water adsorption behavior of m-Sr2[4Ru], which has a three-dimensional lattice structure c...
