摘要

High-pressure solid-phase polymerization directly converts a dinuclear gold complex into a gold-backboned polymer with each chain containing over 100 gold atoms

whose one-dimensional Au backbone enables efficient electron delocalization and broad phosphorescence.

Abstract

Metal-backboned polymers

featuring one-dimensional atomic chains held together by metal–metal bonds

represent a highly promising class of functional materials. However

current synthetic methods rely on solution-phase multidentate bridging ligands

which severely limit the degree of polymerization. Herein

we report a pressure-driven solid-phase polymerization strategy that directly forms intermolecular Au―Au bonds from a dinuclear gold precursor at a pressure of 25 GPa

yielding a gold-backboned polymer (GBP). This method produces a continuous one-dimensional gold chain comprising more than 100 gold atoms. The peripheral ligands coordinate around the backbone

stabilizing the chain and endowing the polymer with high solution processability. The resulting GBP exhibited high thermal stability

well-defined glass transition temperature

and broad-spectrum photoluminescence spanning from the visible to near-infrared regions. This study opens a new synthetic route to long-chain metal-backboned polymers and provides a structurally well-defined model system for investigating the intrinsic photophysical properties of one-dimensional metal–metal bonds.
