In situ formation of new organic ligands to construct two novel self-charge-transfer Pb(II)-based frameworks

Employing in situ-formed new organic ligands, two Pb(II)-based metal-organic frameworks were synthesized. Compound 1 possesses a 3D framework while compound 2 has a layered structure. Solid state UV-visible absorptions indicate that the two compounds are semiconductors with band gaps of 1.70 and 1.78 eV. Magnetic properties reveal that they are temperature-independent diamagnetic.
