Synthesis, Crystal Structure, and Photoluminescent Properties of a Tetracarbonyl(naphthyridylcarbamoyl)rhenium(I) Complex and a Highly Emissive Tetracarbonyl(naphthyridylamido)rhenium(I) Complex

Abstract

The reactions of Re(CO) 5 X (X = Cl, Br) with 7-amino-2,4-di-

Carbon nitride as a ligand: edge-site coordination of ReCl(CO)3-fragments to g-C3N4

“…In addition, to model direct coordination to g-C 3 N 4 , we have also investigated coordination to the commercially available ligand 5, 7-dimethyl-[1, 8]-naphthyridin-2-amine (DMNA) (Scheme 2), which contains a similar structural motif and hence has been chosen as a model for g-C 3 N 4 binding mode(s). 10 The preparation of g-C 3 N 4 was achieved using a literature procedure via the thermal degradation of urea (see experimental section in the ESI †). 11 Characterisation by powder X-ray diffraction (PXRD), elemental analysis, solid state 13 C NMR and scanning electron microscopy (SEM) (see details in the ESI †) is consistent with that reported for g-C 3 N 4 comprised primarily of the melon structural motif (Scheme 1).…”

Aggregation‐Induced Photoluminescent Changes of Naphthyridine–BF2 Complexes

“…The application of these complexes in optoelectronic devices such as OLEDs is currently under investigation. [16][17][18] CCDC-855326 (1-B), CCDC-855327 (1-N) and CCDC-880450 (2) contain the supplementary crystallographic data for this paper. These data can be obtained free of charge from The Cambridge Crystallographic Data Centre via www.ccdc.cam.ac.uk/data_request/cif.…”

Synthesis, crystal structures, and electronic spectra of (1,8-naphthyridine)ReI(CO)3Cl and [(1,8-naphthyridine)CuI(DPEPhos)]PF6

“…Nap and its derivatives can act as monodentate [3][4][5][6], bidentate [5][6][7][8] and dinuclear bridging [3,5,[9][10][11] ligands. Due to this variability of binding and the ease of preparation, the nap moiety is a versatile building block for several ligand systems [12][13][14][15][16][17][18] yielding complexes which display interesting structural [3][4][5][6][7][8][9][10], magnetic, [9] luminescent, [17] catalytic [11,19] and electrochemical [8,13,18,20] properties. For instance, nap is frequently used as a bridging ligand in Rh I -and Ni II -complexes, where a close metal contact is achieved by the geometrical demand of the ligand.…”
