Formation of Enantiomerically Pure Luminescent Triple-Stranded Dimetallic Europium Helicates and Their Corresponding Hierarchical Self-Assembly Formation in Protic Polar Solutions.

Ditopic helicate ligands and were synthesized for the formation of dinuclear Eu luminescent chiral helical assemblies (Eu·L) in competitive organic and protic solvent media. Spectroscopic analysis revealed formation of the 2:3 (Eu·L) and 2:2 (Eu·L) species in methanolic solutions. Circular dichroism and circularly polarized luminescence (CPL) spectroscopy confirmed the chiral purity of the helical systems, while scanning electron microscopy imaging demonstrated the formation of hierarchical self-assemblies with spherical morphologies.

Recent advances in the development of luminescent lanthanide-based supramolecular polymers and soft materials.

Combination of different properties has always proven effective in the generation of hybrid materials with novel interesting properties. Ln(iii) containing materials possessing multiple properties are useful in a wide range of applications. In this article, key and recent examples of metallo-supramolecular polymers in the formation of gels, soft polymeric materials and films are discussed.

Norbornene chaotropic salts as low molecular mass ionic organogelators (LMIOGs).

Phenylalanine functionalised norbornene () functions as a potent, low molecular-mass ( = 333 Da) ionic organogelator with a minimum gelating concentration of 0.5 wt% in THF, -PrOH, 1,4-dioxane and -BuOH. Fibrous crystals form in the gel and X-ray crystallography identified a cation mediated helical assembly process controlled by the chirality of the phenylalanine.

Supramolecular coordination polymers using a close to 'V-shaped' fluorescent 4-amino-1,8-naphthalimide Tröger's base scaffold.

A V-shaped 4-amino-1,8-naphthalimide derived dipyridyl ligand comprising the Tröger's base structural motif has been synthesised and subsequently used in the formation of two new supramolecular coordination polymers.

A supramolecular Tröger's base derived coordination zinc polymer for fluorescent sensing of phenolic-nitroaromatic explosives in water.

A V-Shaped 4-amino-1,8-napthalimide derived tetracarboxylic acid linker (; bis-[-(1,3-benzenedicarboxylic acid)]-9,18-methano-1,8-naphthalimide-[,][1,5]diazocine) comprising the Tröger's base (TB) structural motif was rationally designed and synthesised to access a nitrogen-rich fluorescent supramolecular coordination polymer. By adopting the straight forward precipitation method, a new luminescent nanoscale Zn(ii) coordination polymer () was synthesized in quantitative yield using Zn(OAc)·2HO and tetraacid linker (1 : 0.5) in DMF at room temperature.
