Terpyridine (tpy)-based 3D discrete metallosupramolecular architectures, which are often inspired by polyhedral geometry and the biological structures found in nature, have drawn significant attention from community of chemistry. Because linear tpy-M(II)-tpy connectivity, creation sophisticated metallosupramolecules based on tpy remains a formidable synthetic challenge. Nevertheless, with recent advancement ligand design self-assembly, diverse polyhedrons, such as Platonic solids, Archimedean prims well Johnson been constructed their potential applications explored. This review summarizes progress tpy-based metallosupramolecules, aiming to shed more light construction novel architectures molecular-level precision through coordination-driven self-assembly.

Single crystals with chiral shapes aroused the interest of chemists due to their fascinating polarization rotation properties. Although formation large-scale spiral structures is considered be a potential factor in crystals, precise mechanism behind remains elusive. Herein, we present rare phenomenon involving multitransfer and expression chirality at micro-, meso-, macroscopic levels, starting from carbon atoms extending double-helical secondary structure, ultimately resulting geometry crystals. The assembly double helices facilitated by dual characteristics amide groups derived amino acids, which serve as both hydrogen bond donors receptors, similar pattern observed DNA. Crystal face analysis theoretical morphology reveal two critical factors for crystal: inherent intrinsically symmetrical distribution crystal faces acquired growth. Importantly, magnetic circular dichroism (MCD) study reveals strong magneto-optical response hypersensitive f-f transition UV-vis-NIR region, much stronger than previously signals. Remarkably, an external field can reverse CD signal. This research highlights lanthanide-based helical promising materials.

Entangled (M3 L2 )n polyhedral complexes represent a unique class of supramolecular architectures that are stabilized by relatively weak metal-acetylene interactions in cooperation with conventional metal-pyridyl coordination. Counter-anion exchange these nitrate (NO3- ) ion triggered formal metal insertion between the centers, and heteroleptic ternary coordination mode acetylenic, pyridyl, donors was generated on centers. As result, main frameworks M18 L12 M12 L8 were formally extended into new series concave polyhedra having compositions M21 M13 , respectively. This transformation also resulted local disconnection highly entangled trifurcate topology framework, providing clues toward skeletal editing complex three-dimensional (3D) architectures.

Abstract A saddle‐shaped π‐extended zinc porphyrin containing a peripheral pyridyl ligand undergoes quantitative self‐assembly into cyclic trimer. The trimer has prismatic structure with negatively curved side walls, which promote the formation of supramolecular organic frameworks stabilized by dispersion interactions. first framework type, UWr‐1 , npo topology, hexagonal analogous to Schwartz H triply periodic minimal surface.
