Problems solved by technology

And when there are magnetic metal ions in the fluorescent complex, such as Ni 2+ ,Co 2+ and Cu 2+ etc., the d orbitals of these metal ions are in an unsaturated state, which often induces electron transfer, resulting in fluorescence quenching
Therefore, designing and synthesizing bifunctional complexes with fluorescence and magnetism is of great significance, but at the same time there are great challenges
