Abstract

Self-assembled monolayers (SAMs) of thiol-derivatized porphyrin molecules on Au substrate have attracted extensive interest for use in sensing, molecular recognition, and molecular electronics. Here, we synthesized tetra[p-(3-mercaptopropyloxy)phenyl]porphyrin (PPS₄) with four "clips" for SAMs. The results demonstrated that PPS₄ could form excellent SAMs on gold surface wherein the molecules oriented on substrates with a tilted angle. Self-assembled nanojunctions of PPS₄ were fabricated by using gold nanogap electrodes (gap width: ca. 100 nm), which exhibited nonlinear current-voltage characteristics, indicating tunneling injection of current from Au electrodes into PPS₄. With the light on/off, the nanojunctions switched between low/high impedance states as nanometer scaled photoswitchers.
