We report the first example of photo-induced carbocation-enhanced charge transport in triphenylmethane junctions using the scanning tunneling microscopy break junction (STM-BJ) technique.

The authors propose 4-alkoxy-3,5-diisopropyl-phenyl (DIPP) group as the most suitable substituent to realize porphyrin based advanced materials (PAMs). Our experiments reveal that DIPP achieved the introduction of the following properties on porphine and/or PAMs: (1) easy synthesis, (2) high solubility, (3) good crystallinity natures, and (4) single molecule visualization by scanning tunneling microscopy.
