Metallopolymers and use thereof

Abstract

Metallopolymers of formula (I) where R1 and R1′; and R2 and R2′ are independently of each other, a C2-C10 alkyl group; X is CR3R3′ or NR4; R3 and R3′ are, independently of each other, as is R4, a C2-C10 alkyl group; L is a C4-C10 alkylene group; Ln1 and Ln2 are, independently of each other, chosen from the lanthanide cations; L1 and L2 are, independently of each other, chosen from the α-diketonate ligands; T is a neutral bidentate Lewis base including two coordinating nitrogen atoms; → represents a coordination of group T via the two nitrogen atoms of T to Ln1 and Ln2 respectively; Ln1 and Ln2 are, independently of each other, chosen from the lanthanide cations; L1 and L2 are, independently of each other, chosen from the β-diketonate, picolinate or dipicolinate monoanionic ligands; 0.01<x<0.50; 0<y<0.49, with x+y=0.50.
