DNA intercalating near-infrared luminescent lanthanide complexes containing dipyrido[3,2-a:2′,3′-c]phenazine (dppz) ligands : synthesis, crystal structures, stability, luminescence properties and CT-DNA interaction Ghent University
In order to create near-infrared (NIR) luminescent lanthanide complexes suitable for DNA-interaction, novel lanthanide dppz complexes with general formula [Ln(NO3)(3)(dppz)(2)] (Ln = Nd3+, Er3+ and Yb3+; dppz = dipyrido[3,2-a:2 ',3 '-c]phenazine) were synthesized, characterized and their luminescence properties were investigated. In addition, analogous compounds with other lanthanide ions (Ln = Ce3+, Pr3+, Sm3+, Eu3+, Tb3+, Dy3+, Ho3+, Tm3+, ...
