Design and photophysical investigation of dipyrromethenates coordinated with the boron(III), zinc(II) and cadmium(II) as optical elements

Alkyl-halogen-dipyrromethene (Dpm) ligands coordinated with boron(III), zinc(II), and cadmium(II) were studied experimentally and theoretically to elucidate and compare influence of the coordination centers and halogen substituents (“heavy” atom effect) on observable photophysical properties. Novel and recently published experimental data were summarized and analyzed using quantum-mechanical calculations which revealed specific of the electronic structures and photo-induced dissipations in the molecular complexes.
