title: Color-Tunable Heterodinuclear Pt(II)/B(III) and Pt(II)/Ir(III) Arrays with N^O-julolidine Ligands.
abstract: The synthesis and photophysical properties of two multichromophoric systems, Pt(II)/B(III) and Pt(II)/Ir(III), based on novel N^O-julolidine ligands are reported. The functionalization of the julolidine core enables the introduction of two different anchoring sites, a terminal acetylene and an N^O chelating moiety, which allow the assembling of two different chromophoric centers. The complex photophysical behavior of these multicomponent arrays is rationalized by investigating a series of model compounds, which are prepared through specific synthetic pathways. The photophysical properties of the final multicomponent arrays are investigated in parallel with the models. The multichromophoric system, composed by a platinum(II) and an iridium(III) chromophore connected through a modified julolidine ditopic ligand, displays a peculiar excitation wavelength dependent luminescence behavior. It exhibits tuning of the emission color from blue to orange, passing through pure and warm white.
