macrobicyclic cryptand-type organiccages display remarkable self-sorting behavior with efficient component selection. Making use of the dynamic covalent chemistry approach, eight different cages were synthesized by condensation of tris(2-aminopropyl)amine with structurally different dialdehydes. A series of self-sorting experiments were first carried out on simple dynamic covalent libraries. They reveal

Dynamic covalent component self-sorting processes have been investigated for constituents of different cyclic orders, macrocycles and macrobicyclic cagesbased on multiple reversible imine formation. The progressive assembly of the final structures from dialdehyde and polyamine components involved the generation of kinetic products and mixtures of intermediates which underwent component selection and
Polyaza macrobicyclic cryptands: synthesis, crystal structures of a cyclophane type macrobicyclic cryptand and of its dinuclear copper(I) cryptate, and anion binding features
Multiple (amine + aldehyde) condensation gives the macrobicyclic cryptands (1) and (3) in high yield; (1) gave a dinuclear CuI cryptate and was reduced to a polyamine (2) which binds anions, when protonated.

Seven lathanide cryptates [LnL](NO)(3) . nH(2)O (n = 1-3; Ln = La, Ce, Pr, Sm, Eu, Gd, Tb) were synthesized by the reactions of lanthanide nitrates with free ligand L (L was derived from the (2 + 3) condensation of 2,6-diformyl-pyridine (dfp) with tris-(2-aminoethyl) amine (tren)) and characterized by physical methods. ES-MS spectra show that except for La(III) cryptate, the other six are all stable in solution. The crystal structure of the Eu(III) cryptate showed a tricapped prismatic coordination geometry.
