AI Article Synopsis
- Depositing titanyl phthalocyanine (TiOPc) on a silver surface forms a honeycomb structure with two tilt angles, serving as a template for directing C(70) growth.
- The resulting C(70) films exhibit unique kagome lattice patterns, which are analyzed using advanced imaging techniques.
- This approach leverages electrostatic features of molecular templates to effectively control the organization of nanoscale films through anisotropic interactions.
Article Abstract
Controlled deposition of titanyl phthalocyanine (TiOPc) on Ag(111) produces a honeycomb monolayer phase consisting of TiOPc molecules with two distinctive tilt angles. This periodic arrangement of polar molecules is used to direct C(70) growth into low-density 3D films with novel C(70) kagome lattice arrangements. Structural models for the C(70) kagome lattice are determined from layer-by-layer scanning tunneling microscopy images and related to the dipolar TiOPc template and C(70)'s anisotropic polarizability. Molecular templates with designed electrostatic features offer a practical method to control 3D film organization on the nanoscale by harnessing anisotropic molecular interactions at the growth interface.
