Large-scale synthesis of polyynes with commercial laser marking technology
文献摘要：
The space-confined synthesis method has been an efficient way for the preparation of linear carbon chains.However,the large-scale preparation of linear carbon chains still faces many challenges due to the lack of methods for the large-scale synthesis of precursors,such as short carbon chains(polyynes),and regulation technology for the transport of reactants in one-dimensional space.Here,we report a facile method for the rapid preparation of polyynes in large quantities using a commercial laser marking machine.Spectroscopic characterizations show that a large number of polyynes,such as C8H2,C10H2,C12H2,and C14H2,can be produced by ablating the graphite plate immersed in the organic liquid using a laser marking machine.The results of in situ Raman spectroscopy investigation of C2nH2-filled single-walled carbon nanotubes further confirm that a variety of polyyne molecules are synthesized.Meanwhile,in situ Raman spectroscopy also shows that the local heating treatment can accelerate the filling process of C2nH2 into one-dimensional channels.This work provides new insights into the study of linear carbon chains and space-confined synthesis methods.
