Title

Effective enhancement of near-infrared emission by carbazole modification in the Zn–Nd bimetallic Schiff-base complexes

Language

Abstract

With ZnL 1 or ZnL 2 from the simple Salen-type Schiff-base ligand H 2L 1 (H 2L 1 N,N′-bis(3-methoxysalicylidene)-ethylene-1,2-diamine) or the carbazole-modified Salen-type Schiff-base ligand H 2L 2 (H 2L 2 N,N′-bis(3-methoxy-5-{2-[4-(N-carbazyl)- phenyl]-ethynyl}-ethylene-1,2-diamine) as the precursor, two series of four bimetallic ZnLn complexes (Ln=Nd(1 or 3), Ln=Gd (2 or 4) are obtained, respectively. The photophysical properties results showed that the sensitization from the excited state ( 1LC and 3LC) of the ligand H 2L 1 or H 2L 2 and the effective energy transfer of Zn 2+-Schiff-base (ZnL 1 or ZnL 2) to the Nd 3+ ion for the NIR luminescence were realized, respectively. Especially through the cabarzole modification, the improved NIR luminescence of the ZnNd complex 3 was observed due to the realization of the energy level's match of the excited state of the chromophore to the Nd 3+ ion's exciting state. © 2012 Elsevier B.V.
