Among the plethora of photochromes reported so far, azobenzene has been proven to be the most suitable photoswitch for molecular systems and materials, due to its highly efficient and clean E-Z photoisomerization. Here we report two ammonium-based molecular axles bearing one or two p-cyanoazobenzene units at the extremities, able to form pseudorotaxanes with a crown ether macrocycle. The photochemistry of these compounds was studied in the isolated forms and in the pseudorotaxanes, showing that the functionalization speeds up the threading process without affecting the photochemical properties of the system. These results suggest that the investigated pseudorotaxanes can form the basis of new prototypes of artificial molecular-level pumps.
Reversible Photoswitching of Rotaxane Character and Interplay of Thermodynamic Stability and Kinetic Lability in a Self-Assembling Ring-Axle Molecular System
the results of these experiments with those observed upon dethreading the (pseudo)rotaxane by using a competitive guest for the ring, an approach which does not inherently destabilize the ring–axle interaction. This study outlines a general strategy for the reversible photochemical control of motion kinetics in threaded and interlocked compounds and constitutes a starting point for the construction of

A black resin composition capable of forming a black matrix having high OD value and high adhesion as well as high resistance is disclosed. The black resin composition is a black resin composition comprising at least a light shielding agent, a resin and a solvent, which light shielding agent contains at least titanium nitride compound particles, wherein the angle of diffraction 20 of the peak originated from (200) plane of the titanium nitride compound particles when CuKα line is used as the X-ray source is not less than 42.5° and not more than 42.8°. Using this black resin composition allows a thin resin black matrix having a high light shielding property and high resistance to be readily attained.
