Scanning probe microscopy (SPM) permits real space structural and electronic characterizations at surfaces. Based on SPM studies, this dissertation presents intriguing insights into molecular self-assembly, single molecule chemistry, and functional materials. Atomic-level structural analyses by non-contact atomic force microscopy identify molecular adsorption conformations, bonding motifs in porphyrin oligomers and the molecular structure of planarized porphyrin derivatives uncovering a hitherto unreported tripyrrolic fragment. Finally, scanning tunneling microscopy manipulation experiments demonstrate the nanoscale phase engineering of a transition metal dichalcogenide to create atomically sharp homo junctions.
