| 英文摘要 | Two-dimensional (2d) self-assembled 1,3,5-tris(10-carboxydecyloxy) benzene (tcdb) networks connected by hydrogen bonds on highly oriented pyrolytic graphite (hopg) surfaces are shown to accommodate a variety of unsubstituted metallophthalocyanine (mpc) molecules (such as h2pc, cupc, vopc, and clgapc) and halogen-substituted mpcs (such as f16cupc, which have been observed by scanning tunneling microscopy (stm) under ambient conditions. two types of dramatically different host-guest architectures are identified for each mpc/tcdb systems, that is, the architecture mpc/tcdb (i) (with mpc monomers entrapped in the tcdb cavities) and the architecture mpc/tcdb (ii) (with mpc dimers entrapped in the tcdb cavities). the intermolecular interactions are calculated by density functional theory (dft), which demonstrates that the host-guest intermolecular interactions (including van der waals forces and electrostatic interactions caused by asymmetrical electronic distribution of mpcs) are important in determining the on-and-off of hydrogen bonds in the host lattice. the stm study combined with the dft calculations reveal that the hydrogen bond switching through o-h center dot center dot center dot o bonds is responsible for the formation of tcdb cavities with multiple flexibility for guest molecule inclusion. |
