Facile Preparation of Organometallic Nanorods from Various Ethynyl‐Substituted Molecules
Abstract A facile method to prepare one‐dimensional (1D) organometallic nanomaterials from various ethynyl‐substituted molecules is reported. The reactions of 3‐chloro‐1‐ethynylbenzene, p‐tBu‐phenylacetylene and 4‐ethynylbiphenyl with Cu+ ions in acetonitrile yield nanorod‐shaped copper acetylides (...
