| Abstract |
A new strategy for inner-cavity control of coordination cages using various alkyl sulfates as a molecular glue has been carried out. Self-assembly of palladium(II) nitrate with new tridentate 1,3,5-tris(4-nicotinamide-phenoxy)benzene (L) produces [Pd6L8]12+ cages with the inner cavity of 19 × 21 × 25 Å3. The addition of alkyl sulfates (ROSO3-, R = ethyl-, octyl-, decyl-, dodecyl-, and tetradecyl-) produces a host-guest interaction assembly, inducing the cavity contraction of the coordination cages with the inner cavity of 13 × 13 × 13 Å3. This cage specifically binds to the sulfate moiety via hydrogen bonds between O of the sulfate and H of the amide, enabling the cage to recognize the alkyl length of the alkyl sulfates. The contact angles of a drop of liquid on the surface of crystalline solid are strongly depending on the alkyl chain length of the included alkyl sulfates. |
