Design of nano-scaled devices based on gold nanoparticles (AuNP) cross-linked with functional molecules received considerable attention during recent years. 2D and 3D arrays of AuNP allowed the creation of downscaled contact electrodes, touch sensors as well as optically-, chemically- and mechanically-controlled resistors. Herein we present a stepwise approach towards nanoswitches with optically modulated electron conductance. Such switches are a combination of two gold nanoelectrodes (modeled with AuNPs) linked by photochromic diarylethene molecules (DAE). DAE can be switched reversibly between low- (open-ring form) and higher (closed-ring form) electron conductance states under visible and UV light irradiation, respectively. However, developing of nanoswitches requires: (i) optimization of molecular structure, (ii) stress testing of DAE in contact with gold nanoelectrodes under alternating UV-/visible light irradiation, i.e. variance of conductance, (iii) development of suitable verification of opto-electronical properties of designed nanodevice.
