Zusammenfassung
The complex (dmp)Cu-1(BH4) with dmp=2.9-dimethyl-1.10-phenanthroline displays a long-wavelength absorption at 465 nm which is assigned to a BH4 --> dmp ligand-to-ligand charge transfer (LLCT) transition. In the solid state the LLCT state is emissive (lambda(max)= 626 nm), In non-coordinating solvents such as CH2Cl2, CHCl3 or toluene the complex undergoes a photoredox decomposition leading to the ...

The complex (dmp)Cu-1(BH4) with dmp=2.9-dimethyl-1.10-phenanthroline displays a long-wavelength absorption at 465 nm which is assigned to a BH4 --> dmp ligand-to-ligand charge transfer (LLCT) transition. In the solid state the LLCT state is emissive (lambda(max)= 626 nm), In non-coordinating solvents such as CH2Cl2, CHCl3 or toluene the complex undergoes a photoredox decomposition leading to the generation of metallic copper, At lambda(irr) = 436 nm (dmp)Cu-1(BH4) disappears with phi = 1.2 x 10(-3).
