文摘The backbones of polymers are generally composed of non-metal elements such as C,N,O and Si.Here we propose and synthesize a new class of polymers whose backbones are completely made from metal atoms connected by chemical bonds,and they are thus named metal-backboned polymers.As a demonstration,nickel is selected as the metal to construct the nickel-backboned polymers with varied lengths,which are verified by mass spectrometry and studied by ultraviolet-visible spectroscopy.These metal-bonded polymers open up a new avenue to develop functional polymers in the future.
