Abstract

A series of novel Wolf Type II Ln3+-containing metallopolymers PNBE-co-Ln4(Salen)4 (Ln = La, Nd, Yb, Er or Gd) are obtained from the controlled ring-opening metathesis polymerization (ROMP) of norbornene (NBE) and the homoleptic tetranuclear [Ln4(L) 2(HL)2Cl23-OH) 2]·2Cl (Ln4(Salen)4, Ln = La, 1; Nd, 2; Ln = Yb, 3; Ln = Er, 4; Ln = Gd, 5) self-assembled from the diallyl-modified flexible hexadentate Salen-type Schiff-base ligand H2L (N,N′-bis(5-allyl-3-methoxysalicylidene)cyclohexane-1,2-diamine) with LnCl3·6H2O. The results of their photophysical properties show that the strong and characteristic near-infrared (NIR) luminescent Ln3+-centered emissions for PNBE-co-Ln 4(Salen)4 (Ln = Nd, 2; Yb, 3) are retained with relatively higher intrinsic quantum yields than the corresponding monomers in solution, and the concentration self-quenching of Ln3+-based materials could be effectively prevented in both solution and solid states.
