NOVEL METALLOPOLYMERS AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2014/122406
Kind Code:
A3
Abstract:
The invention concerns metallopolymers of formula (I) in which R1 and R1 are, independently of each other, a C2-C10 alkyl group; 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, a C2-C10 alkyl group; R4 is 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 comprising 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; x is between 0.01 and 0.50; y is between 0 and 0.49, the sum of x+y being equal to 0.50, and the use thereof in polymer light-emitting diodes.
