Asymmetric, heteroleptic dinuclear bis(dipyrrinato)zinc(II) complexes were synthesized and demonstrated to collect a wide range of light across the UV and visible regions (340-655 nm). The complexes also conveyed excitons across their structure from one end to the other, with spectroscopic studies demonstrating quantitative and fast energy transfer.
New heteroleptic zinc dimeric complexes bearing an aminophenolate ligand of a single-site initiator framework were synthesized and characterized by spectroscopic methods, X-ray analysis, and DFT calculations. The theoretical study, verified by the experimental data, explains the catalytic behaviour in the ROP of lactide in the examined zinc complexes. The presented simple DFT protocol constitut...
The straightforward synthesis and photophysical properties of a new series of heteroleptic iridium(III) bis(2-arylimidazole) picolinate complexes are reported. Each complex has been characterized by nuclear magnetic resonance, UV-vis, cyclic voltammetry, and photoluminescent angle dependency, and the emissive properties of each are described. The preferred orientation of transition dipoles in e...
Coordination-driven self-assembly of metal ions and organic ligands has been extensively applied over the past few decades, towards construction various functional two-dimensional (2D) three-dimensional (3D) architectures. The majority these structures are homoleptic in nature, consisting one type ligand. However, functionality self-assembled complexes can be potentially increased by increasing...
The highest efficiency ever reported for an iron-sensitized solar cell has been obtained using a Fe(ii) pyridylNHC-carboxylic heteroleptic complex. Mg2+ cations and NBu4I in the electrolyte, substantially boosted photocurrent.
Subjecting furan to sodium-mediated magnesiation via the new heteroleptic alkyl-amido reagent [(TMEDA).Na(CH(2)SiMe(3))(TMP)Mg(TMP)] produces the remarkable dodecasodium-hexamagnesium molecule [{(TMEDA)(3)Na(6)Mg(3)(CH(2)SiMe(3))(2,5-C(4)H(2)O)(3)(2-C(4)H(3)O)(5)}(2)], built upon a bridge network of 10 monodeprotonated and 6 twofold-deprotonated furan ligands.
Using a transamination approach to access novel Fe(ii) complexes, this study presents the synthesis, X-ray crystallographic and magnetic characterisation of a series of new iron complexes containing the multifunctional 2,2-dipyridylamide (DPA) ligand using iron bis(amide) [{Fe(HMDS)2}2] and sodium ferrate [{NaFe(HMDS)3}∞] (1) as precursors (HMDS = 1,1,1,3,3,3-hexamethyldisilazide). Reactions of...
