Lanthanide luminescent di-metallic triple-stranded helicates formed from bis-tridentate (1,2,3-triazol-4-yl)-picolinamide (tzpa) ligands and their higher order self-assemblies†
The bis-tridentate (1,2,3-triazol-4-yl)-picolinamide (tzpa) ligands 1 and 2 were used in the formation of the luminescent di-metallic Tb(III) triple stranded helicates 3 and 4 (L3Tb2; L = 1 or 2). Both 3 and 4 were formed in high yield under either kinetic or thermodynamic conditions and their binding constant values were evaluated. The photophysical properties of the assemblies were analysed in the solution and solid state. The morphology of the ligands vs. the Tb(III) assemblies were significantly different as detected by SEM.
期刊介绍:
Materials Chemistry Frontiers focuses on the synthesis and chemistry of exciting new materials, and the development of improved fabrication techniques. Characterisation and fundamental studies that are of broad appeal are also welcome.
This is the ideal home for studies of a significant nature that further the development of organic, inorganic, composite and nano-materials.
