摘　　要：In order to assess the dynamics of molecular conversion,scientists simulated the low-temperature synthesis of polycyclic aromatic hydrocarbons(PAHs)in Titan’s atmosphere[1],and noticed the transformation(hydrogenation,oxygenation,and hydroxylation to complex molecules)of PAHs under interstellar medium conditions.Geological hydrothermal systems have also drawn attention as potential key sites for various organic synthesis and transformation reactions[2,3].Thus the formation of abiotic CH4[4],which has proven to be an important component of deep hydrothermal fluids that are generated outside the temperature regime envisaged for thermogenic gases,have long been reported in a range of global hydrothermal sites,including mid-ocean ridges,continental rifts,pre-orogenic and subduction zones,back-arcs,hot springs,and volcanically-active areas.These transformation processes have been suggested to occur at the water–mineral interface.There is compelling evidence for the generation of C-H chain molecules from inorganic chemicals via abiotic reactions(e.g.,Fischer-Tropsch synthesis of CH4)in laboratory and field studies[5,6].However,a huge gap remains in the understanding of carbon and hydrogen evolution and heterocyclization from C-H chain molecules to complex heterocyclic materials and then possible hydrophobic or hydrophilic macromolecules,and the corresponding reaction mechanism(s).The occurrence of abundant and complex heterocyclic molecules formed through abiotic processes is rare in natural regions associated with deep fluid movement and activity。
