Complexes with ligand-to-metal charge-transfer (LMCT) excited states involving d0 metals represent a new design for photocatalysts. Herein, the photochemistry and photophysics of titanocenes type Cp2Ti(C2R)2, where C2R = ethynylphenyl (C2Ph), 4-ethynyldimethylaniline (C2DMA), or 4-ethynyltriphenylamine (C2TPA), have been investigated. Cp2Ti(C2Ph)2 Cp2Ti(C2DMA)2 also characterized by single-crystal X-ray diffraction. The two aryl rings in are nearly face-to-face solid state, whereas they...
Transition-metal complexes that undergo ligand-to-metal charge transfer (LMCT) to d0 metals are of interest as possible photocatalysts due the lack deactivating d-d states. Herein, synthesis and characterization nine titanocene formula Cp2Ti(C2Ar)2·MX (where Ar = phenyl, dimethylaniline, or triphenylamine; MX CuCl, CuBr, AgCl) presented. Solid-state structural demonstrates coordinates alkyne tweezers CuX coordination has a greater impact than AgCl. All complexes, including parent without...
Complexes that undergo ligand-to-metal charge transfer (LMCT) to d0 metals are of interest as possible photocatalysts. Cp2Ti(C2Ph)2 (where C2Ph = phenylethynyl) was reported be weakly emissive in room-temperature (RT) fluid solution from its phenylethynyl-to-Ti 3LMCT state but readily photodecomposes. Coordination CuX between the alkyne ligands give Cp2Ti(C2Ph)2CuX (X Cl, Br) has been shown significantly increase photostability, such complexes not RT solution. Herein, we investigate whether...
