Applications to Biological Models

On many occasions, and this is certainly correct for 2-nitrobenzyl derivatives, photocleavable groups can be eliminated under mild conditions (aqueous media, neutral pH, and low temperature). Frequently, at a sufficiently long wavelength, only the bond designated for cleavage is affected by irradiation, so that, whenever the irradiation itself and the photoproducts formed are not harmful to the biological system (such as cells,

Inclusion complexes are chemical species consisting of two or more associated molecules in which one of the molecules, the host, forms or possesses a cavity into which it can admit a guest molecule, resulting in a stable association without formation of any covalent bonds. Secondary forces are alone responsible for maintenance of the integrity of all inclusion complexes. 

Over the past twenty-five years, interest in the physical and chemical properties of inclusion complexes has grown considerably. One of the most important reasons for this is the relevance that inclusion complexes
