Bis(benzotriazol-1-yl)phenylmethane CHPh(btz)2 and tris(benzotriazol-1-yl)methane CH(btz)3 were used as N-donor ligands to prepare luminescent heteroleptic copper(I) complexes. [Cu{CHPh(btz)2}(PPh3)2][BF4] [Cu{CHPh(btz)2}(DPEphos)][BF4] (DPEphos = bis[(2-diphenylphosphino)phenyl] ether) obtained from the corresponding borohydride complexes [Cu(BH4)(PPh3)2] [Cu(BH4)(DPEphos)] tetrafluoroboric ac...

Syntheses of heteroleptic 1,8-bis(phosphino)naphthalenes and 5,6-bis(phosphino)acenaphthenes were attempted using several synthetic strategies. Reaction of aryllithium with triphenylphosphite gave ArP(OPh)(2) (Ar = substituted naphthalene or acenaphthene), which was transformed into ArP(CF(3))(2), using a nucleophilic trifluoromethylation reaction with Me(3)SiCF(3)/CsF. The importance of the co...

Cyclometalated Ir(III) complexes are of particular interest due to the wide tunability of their electronic structure via variation of their ligands. Here, a series of heteroleptic Ir-based photosensitizers with the general formula [Ir(CN)2(N ∧N)]+ has been studied theoretically by means of an optimally-tuned long-range separated density functional. Focusing on the steady-state absorption spectr...

A triptycene-based bis(benzoxazole) diacid ligand H(2)L2(Ph4) bearing sterically encumbering groups was synthesized. Treatment of H(2)L2(Ph4) with Fe(OTf)(3) afforded a C(2)-symmetric trinuclear iron(III) complex, [NaFe(3)(L2(Ph4))(2)(μ(3)-O)(μ-O(2)CCPh(3))(2)(H(2)O)(3)](OTf)(2) (8). The triiron core of this complex adopts the well known "basic iron acetate" structure where the heteroleptic car...

A general introduction to the application of zirconia materials is provided in this chapter with a specific emphasis on the application in membrane and the use of zirconia as a high-k material. The main focus of this thesis is the preparation of suitable heteroleptic alkoxide precursors for the application in sol-gel and metalorganic chemical vapor deposition (MOCVD). Selecting suitable alkoxid...
