Reassembly self-sorting triggered by heterodimerization.

We report herein a five-component self-sorted system comprising molecular clips that form heterodimers 1·4 and 8·11, and homodimer 14·14 in C(6)D(5)CD(3)/CDCl(3). The three component self-sorting mixture comprising 1·1, 8·8, and 14·14 undergoes triggered reassembly self-sorting upon addition of 4·4 and 11·11.

Nanotubular non-covalent macrocycle within non-covalent macrocycle assembly: (MeOH)(12) encapsulated in a molecular clip cyclododecamer.

A noncovalent macrocycle-within-noncovalent macrocycle assembly is formed from twelve molecules of (+/-)-1 and twelve molecules of MeOH in the solid state. The H-bonded (MeOH)(12) cyclododecamer assumes a crown-shaped geometry that has not previously been predicted theoretically or found experimentally.

Diethyl 2,6-(2,4-dichloro-phen-yl)-4,8-dioxo-2,3,6,7-tetra-hydro-1H,5H-2,3a,4a,6,7a,8a-hexa-azacyclo-penta-[def]fluorene-8b,8c-dicarboxyl-ate.

The title mol-ecule, C(28)H(28)Cl(4)N(6)O(6), is built up from four fused rings, viz. two nearly planar imidazole five-membered rings which adopt envelope conformations with the C=O groups at the flap position, and two triazine six-membered rings which adopt chair conformations. Each six-membered ring has a 2,4-dichloro-benzyl substituent attached to an N atom.
