Molecular Tectonics: A Node-and-Linker Building Block Approach to a Family of Hydrogen Bonded Frameworks

While numerous hydrogen bonded organic frameworks (HOFs) have been reported, typically these cannot be prepared predictably or in a modular fashion. In this work, we report a family of nine diamondoid crystalline porous frameworks assembled via hydrogen bonding between poly-amidinium and poly-carboxylate tectons in aqueous media. Importantly, both the cationic and anionic components can be varied and additional functionality can be incorporated into the frameworks, which show good stability including to prolonged heating in DMSO or water.

Chiral tectonics toward square planar tetranuclear Pd(ii) complexes: propagation of axial chirality through a long molecular axis

Tetranuclear Pd(ii)complexes were synthesized according to the molecular tectonics approach. A focus was how the elongation of a molecular axis affected the chiro-optical properties of a molecule with axial chirality.

Molecular tectonics: homochiral 1D and 2D cadmium based coordination networks

By combining enantiomerically pure tectons with Cd(NO3)2, a series of six new homochiral luminescent coordination networks are formed. The dimensionality and crystal packing of the latter are modulated by both the nature of the chiral side chains and the crystallization solvents.

Molecular tectonics: enantiomerically pure chiral crystals based on trans-1,2-cyclohexanediol

Enantiomerically pure trans-1,2-cyclohexanediol ((R,R) or (S,S)) based organic ligands act self-complementary units. In addition, their coordination behavior towards Cd2+ cation in the presence of N donor ancillary ligand was investigated.

Molecular tectonics: from a rigid achiral organic tecton to 3D chiral Co and Fe coordination networks

The combination of an achiral tetradentate coordinating tecton with achiral Co(SCN)2 and Fe(SCN)2 neutral complexes leads to the formation of isostructural crystals composed of 3D helical strands.

Molecular tectonics: control of crystalline sequences

Isostructural and almost isometric crystals that differ in their colour may be welded in solution and under mild conditions into crystalline materials with imposed sequences.
