Photochemical synthesis of diazacryptophane

Azacryptophane was obtained by irradiation of the precursor diammonium chloride in the presence of γ-CD (γ-cycodextrin) in aqueous solution. In the liquid-liquid extraction, the azacryptophane showed a moderate affinity toward all alkali metal picrates without any significant selectivity, whereas it selectively extracted both Ag+ and Pb2+ cations in a series of heavy metal nitrates.
