摘      要：The unveiling of MOF growth mechanism is hampered by the lack of fundamental knowledge about the very early stage of nucleation,especially the form and ratio of molecular species in the solution for crystal ***,we report the detection of growth species for a series of MOFs with mono-linker,CuMOF-2-BDC and Cu-MOF-2-NDC,and two linkers,MTV-MOF-2-(C_(4)H_(4))x,by high resolution ESI-MS,where a large variety of Cu-containing species are identified *** solvent molecules such as H_(2)O,methanol and DMF participate in the formation of these species,other than ***,in the growth solution of MTV-MOF-2-(C_(4)H_(4))x,growth species containing two different organic linkers are *** feeding ratio is not the only factor controlling the distribution of growth species for MTVMOFs,but also the solvent involves in coordination,an aspect usually overlooked previously.
