Abstract	Abstract Through self-assembly of the (OH)2-Salophen H4L (H4L = N, N′-bis(3-hydroxyl salicylidene)benzene-1,2-diamine) with LnCl3·6H2O (Ln = La, Nd, Yb, Er or Gd), series of [Ln4((OH)2-Salophen)4]-arrayed complexes [Ln4(H2L)2(L)2(EtOH)2] (Ln = La, 1; Ln = Nd, 2; Ln = Yb, 3; Ln = Er, 4 or Ln = Gd, 5) were obtained, respectively. The result of their photophysical properties shows that the strong and characteristic NIR luminescence for complexes 2–3 with emissive lifetimes in microsecond ranges is observed, and the sensitization arises from the excited state (1LC) of the (OH)2-Salophen ligand despite the luminescent quenching with OH-oscillators around the Ln3 + ions.
