Abstract (AI)
Ultrathin insulating NaCl films have been employed to decouple individual pentacene molecules electronically from the metallic substrate. This allows the inherent electronic structure of the free molecule to be preserved and studied by means of low-temperature scanning-tunneling microscopy. Thereby direct images of the unperturbed molecular orbitals of the individual pentacene molecules are obtained. Elastic scattering quantum chemistry calculations substantiate the experimental findings.
Key Findings
1
Elastic scattering quantum chemistry calculations support and substantiate the observed molecular-orbital images.
2
Electronic decoupling preserves the intrinsic electronic structure of free pentacene molecules for experimental study.
3
Low-temperature scanning-tunneling microscopy directly images the unperturbed molecular orbitals of individual pentacene molecules.
4
Ultrathin insulating NaCl films electronically decouple individual pentacene molecules from a metallic substrate.
