Photoinduced Ba2+ release and thermal rebinding by an azacrown ether linked by an alkynyl pyridine to a (bpy)Re(CO)3 group.
A novel complex in which an azacrown ether is linked by an alkynyl pyridine to a (bpy)Re(CO)3 group acts as a light-controlled ion switch: Ba2+ bound to the azacrown is released in ca. 10 ns on UV excitation, and rebinds thermally from bulk solution in ca. 1 micros.
