Synthesis, crystal structures and antenna-like sensitization of visible and near infrared emission in heterobimetallic Zn–Eu and Zn–Nd Schiff base compounds

Visible and near infrared (NIR) luminescence are observed in heterobimetallic 3d–4f Schiff base complexes [ZnLEu(OAc)(NO3)2] · EtOH · H2O (2) and [ZnLNd(OAc)(NO3)2(H2O)] · EtOH (3), respectively (H2L = N,N′-bis(5-bromo-3-methoxysalicylidene)phenylene-1,2-diamine, OAc = acetate).
