• ligands; fluorescence; heterocycles; Pd-mediated couling reactions; quinolizinium; Introduction Polycyclic cationic hetarenes are a paradigm of DNA-binding ligands whose association with the nucleic acid may affect the biological activities of the DNA [1][2][3][4]. For example, a DNA-bound heterocyclic
