Metal Cation Complexes with Calixarenes Carrying Substituents on the Lower Rim

2 Metal Cation Complexes with Calixarenes Carrying Substituents on the Lower Rim 

Following shortly on the heels of the early complexation studies with unsubstituted calixarenes were studies with calixarenes carrying substituents on the lower rim. Some involve calixarenes whose pendant arms are unconnected with one another, while others involve calixarenes carrying lower rim bridges of various sorts, as discussed in the following sections.
