Abstract

HAL is a multi-disciplinary open access archive for the deposit and dissemination of scientific research documents, whether they are published or not. The documents may come from teaching and research institutions in France or abroad, or from public or private research centers. L'archive ouverte pluridisciplinaire HAL, est destinée au dépôt et à la diffusion de documents scientifiques de niveau recherche, publiés ou non, émanant des établissements d'enseignement et de recherche français ou étrangers, des laboratoires publics ou privés. 2,2'-Dipyridylamines more than just sister members of the bipyridine family. Applications and achievements in homogeneous catalysis and photoluminescent materialsAbstract 2,2'-Dipyridylamine (dpa) and related compounds belong to the family of polydentate nitrogen ligands. More than a century has passed since its first report but new complexes and applications have been emerging in the recent years owing to the versatility of dpa-based architectures. This review aims to present and highlight the main achievements attained with dpa-containing metal complexes in the domains of homogeneous catalysis and luminescent materials.

Ferrocene conjugates linked by 1,2,3‐triazole and their Zn(II) and Cu(II) complexes: Synthesis, characterization and biological activity

“…Although the dipyridylamine chelating group is a widely used motif in many areas of chemistry, [50][51][52] bis-1,2,3-triazole ligands are much less common and the majority of research done on bis-1,2,3-triazole ligands regards Co(II) and Fe(II) complexes studied as spincrossover systems. [53,54] The reported complexes mainly have ML 2 stoichiometry, and the bis-1,2,3-triazole ligands show a preference for formation of trans-fac isomers.…”

Acceptorless and Base‐Free Dehydrogenation of Alcohols Mediated by a Dipyridylamine‐Iridium(III) Catalyst

“…Alternatively, Kanai reported an original process for the room temperature acceptorless dehydrogenation of alcohols using a hybrid ternary catalytic system. [16] Recently, we have been interested in the synthesis of catalysts bearing chelating dipyridylamine ligands [17,18] in a number of catalytic transformations. 2,2-Dipyridylamine is a non-expensive commercially available compound and 2,2'-dipyridylamine derived ligands are easily accessible using simple synthetic procedures.…”

Design Rule Hidden from The Eye in S/N‐Bridged Ancillary Ligands for Copper(I) Complexes Applied to Light‐Emitting Electrochemical Cells

“…[11][12][13][14][15] In the last decade, research has been focused on heteroleptic Cu(I)-iTMCs combining (i) sterically hindered PˆP ligands, such as bis[(2-diphenylphosphino)phenyl] ether (DPEPhos) or 4,5-bis(diphenylphosphino)−9,9-dimethylxanthene (Xanth-Phos), and (ii) NˆN bidentate ligands, such as bipyridine and dipyridylamine families. [6,9,[16][17][18][19][20] While the bulkiness of the PˆP prevents the flattening distortion at the excited state, [18,21] the NˆN ligand rules the fine-tuning of photophysical properties, such as emission wavelength and photoluminescence quantum yields (ϕ), among others. [9,16,17] Though most of the reported examples have led to green-and yellow-emitting LECs, [22][23][24][25][26] there are a handful of ligand designs for blue- [27] and red- [21] emitting LECs featuring performances as high as 3.6 cd A −1 at luminance of 180 cd m −2 and 0.19 lm W −1 at irradiance of 130 μW cm −2 , respectively.…”
