Case Study 6.30 Photoactivatable compounds - chromatic orthogonality 

4 Amines, Aromatic Nitriles, Metalloorganic Complexes Photoinduced Electron/Charge Transfer 

Aromatic nitriles are typical electron acceptors their electron acceptor abilities increase with increase in the number of electron-withdrawing cyano groups and with 

As part of the search for alternatives to fossil fuel, recent studies have focused on the production of hydrogen, a clean and renewable energy carrier, by direct water splitting 

The great demand for miniaturization of components in electrotechnical, medicinal or material applications has led to the development of a highly multidisciplinary scientific and technological field called nanotechnology to produce devices with critical dimensions within the range 1 100 nm. The ultimate solution to miniaturization is logically a functional molecular machine, an assembly of components capable of performing mechanical motions (rotation or linear translation) upon external stimulation, such as photoactivation.1103,1104,1239-1244 This motion should be controllable, efficient and occur periodically within an appropriate time-scale therefore, it involves photochromic behaviour discussed in the Special Topic 6.15. Such devices can also be called photochemical switches (Special Topics 6.18 and 6.15). Here we show two examples of molecular machines a molecular rotary motor and a molecular shuttle.
