HIGHLY BRANCHED DENDRIMERS

摘要

A dendrimer of formula (I): [DENDRON¹]_x-CORE-[B-[X]_b]_a (I) wherein: CORE is a metal ion or a group containing a metal ion, or is a non- polymeric organic group; B is a phenyl ring; a is an integer of from 1 to 8; b is an integer of from 3 to 5; x is zero or an integer of from 1 to 7; each X is an aryl or heteroaryl ring, or is an at least partially conjugated dendritic molecular structure; each DENDRON¹ is an at least partially conjugated dendritic molecular structure; and wherein the dendrimer further comprises one or more surface groups; with the proviso that where CORE is a non-metallic core, then X is an at least partially conjugated dendritic molecular structure comprising at least one linking group.
