Synthesis, crystal structures and antenna-like sensitization of visible and near infrared emission in heterobimetallic Zn–Eu and Zn–Nd Schiff base compounds
摘要:
Visible and near infrared (NIR) luminescence are observed in heterobimetallic 3d-4f Schiff base complexes [ZnLEu(OAc)(NO3)(2)] center dot EtOH center dot H2O (2) and [ZnLNd(OAc)(NO3)(2)(H2O)] center dot EtOH (3), respectively (H2L = NN'-bis(5-bromo-3-methoxysalicylidene)phenylene- 1,2-diamine, OAc =acetate).
