The synthesis and characterization of novel photochromic diarylethene-based linkers for use in metal–organic frameworks is described including crystal structure analysis of nearly all reaction intermediates.
A series of photochromic phenanthrene derivatives bearing pyridine or pyridinium units have been synthetized and characterized by spectroscopy, electrochemistry and theoretical calculations. It has been demonstrated that the different substitution positions yield to a drastic difference on the photo and electrochromic properties of these systems. These compounds derived from polycyclic aromatic hydrocarbons
Using a mechanically controlled break junction (MCBJ) technique, we have demonstrated a single molecule-based photothermal linear actuator whose conductance remains constant during its operation. The actuation is achieved by the unique design of the molecular system, which allows a perfect balance of molecular length and band gap change upon isomerization that counteracts the effect of one another
