Abstract

Through the self-assembly of the Salen-type Schiff-base compound H2L (H2L = N,N′-bis(3-methoxy-salicylidene)cyclohexane-1,2-diamine) with dehydrated Zn(NO3)2 and Ln(NO3)3 (Ln = La, Yb or Gd), the combination of novel μ3-mode bridging, μ2-chelating and free mode of six NO3- anions induces the formation of three complexes {[Zn2(L)2Ln2((μ3-NO3)22-NO3)2]× 2(NO3)} (Ln = La, 1; Ln = Yb, 2 or Ln = Gd, 3), respectively, where the compacted Zn2Yb2-array of complex 2 endows the good NIR luminescence (ΦLYb = 0.98% and ηsens = 77%).
