Abstract
A series of copper(I) diimine complexes containing benzo-10-thia-15-crown-5, benzo-10-selena-15-crown-5, benzo-10-tellura-15-crown-5 and benzo-7,10,13-trithia-15-crown-5 moieties have been synthesized and characterized and their photophysics and electrochemistry studied. The encapsulation of soft metal ions by the cavity of the complexes has been investigated by electronic absorption and emission spectroscopy. The crystal structures of [Cu(PPh3)2(dic-S)]BF4 and [Cu(PPh3)2(dic-Se)]BF4 have been determined.
