2020年11月1日 · In a previous work, we studied PTCDI on Sn/Si(111)-2 3 × 2 3 using scanning tunneling microscopy (STM) and low energy electron diffraction (LEED). At low coverages single molecules could be found on the substrate, indicating a strong substrate/molecule interaction.

Monolayers of the organic molecules perylene-3,4,9,10-tetra-carboxylic-dianhydride (PTCDA) and diimide (PTCDI) on graphite and MoS 2 have been imaged with scanning tunneling microscopy. The epitaxial growth of the two molecules is determined by the intermolecular interaction but nearly independent of the substrate.

2017年8月29日 · PTCDI molecules and NaCl self-assemble on the Au(111) surface to form two-dimensional porous hybrid nanoarchitectures. Scanning tunneling microscopy (STM) reveals that temperature can drastically influence the structure of these nanoarchitectures. A PTCDI-NaCl flower structure is created after codeposition onto a surface at 20 °C.

2003年8月28日 · We investigate an open honeycomb network formed when perylene tetra-carboxylic di-imide (PTCDI; Fig. 1a) is co-adsorbed with melamine (1,3,5-triazine-2,4,6-triamine; Fig. 1b) on a...

Scanning Tunneling Microscopy (STM), Scanning Tunneling Spectroscopy (STS), and manipulation studies were performed on an ordered self-assembled monolayer (SAM) of N, N ′-bis (1-hexylheptyl)perylene-3,4:9,10-bis (dicarboximide) molecules on epitaxial graphene on hexagonal silicon carbide – SiC (0001).

2008年9月4日 · The adsorption of PTCDI (3,4,9,10-perylene-tetracarboxylic diimide) onto a Au(111) surface templated by two-dimensional (2-D) Ni clusters has been investigated by scanning tunneling microscopy (STM). We found that the nickel coverage has a significant effect on the distribution and stability of the characteristic hydrogen bonding phase of PTCDI ...

2012年11月15日 · Supramolecular self-assembly of the organic semiconductor perylene-3,4,9,10-tetracarboxylic diimide (PTCDI) together with Ni atoms on the inert Au(111) surface has been investigated using high-resolution scanning tunneling …

2004年8月1日 · The formation of ordered structures of large, nonplanar perylene derivative DPP-PTCDI/perylene-3,4,9,10-tetra-carboxylic-diimide-di(2,6-isopropylphenyl)/on Ag(1 1 0) has been studied “in situ” by means of variable temperature STM. The observations of the molecule diffusion and resulting growth behaviour were performed within a wide ...

imide (PTCDI) on graphite and MoS 2 have been imaged with scanning tunneling microscopy. The epitaxial growth of the two molecules is determined by the inter- molecular interaction but nearly independent of the sub- strate. On both substrates the STM image contrast in the

2018年10月28日 · PTCDI molecules were evaporated onto a Ag/Si(111) 3 × 3 surface and studied using scanning tunneling microscopy (STM) and angular resolved ultraviolet photoelectron spectroscopy (ARUPS). High resolution STM images are used to identify the delicate molecule/molecule and molecule/substrate interactions and the shapes of the molecular orbitals.
