| Research Abstract |
By using single crystals of zeolite AlPO4-5 having one-dimensional (1D) micropores with an inner diameter of 0.7 nm, selenium which is a semiconductor material and anthracene that is aromatic molecules are loaded into the pores. Obeying to the small nano-space, we expected the guest materials exhibit anisotropic and unique electronic properties. Electronic state of selenium atoms in the 1D pores was similar to an isolated three fold helix extracted from bulk trigonal Se. In case of loading anthracene molecules, we expected π-π interaction between the adjacent molecules in the 1D pores because of the restricted orientation of the molecules in the small nano-space. Unfortunately, we could observe no phenomena originating from such interaction.
