PHOSPHORS AND PROCESS FOR PRODUCTION THEREOF, LUMINESCENT COMPOSITIONS, AND ORGANIC ELECTROLUMINESCENT DEVICES AND PROCESSES FOR PRODUCTION THEREOF

摘要

Disclosed are phosphors which can easily form thin film by a wet process and give organic electroluminescent devices permitting high-brightness light output, and a process for the production thereof; luminescent compositions containing the phosphors; and organic electroluminescent devices equipped with light-emitting layers containing the phosphors, and processes for the production thereof. The phosphor consists of a polymer containing in the molecule structural units represented by the general formula (1) wherein M is a di- to tetra-valent metal atom; R<1> and R<2> are each hydrogen, halogeno, alkyl, cycloalkyl, aryl, or a heterocyclic group and may be the same or different from each other; X<1> is phenylene or carbonyloxy; X<2> is alkylene; L is an organic ligand; p is an integer of 1 to 3; and q is 0 or 1.
