摘要：

Electronic absorption spectroscopy has been used to study the host-guest interaction of a series of ferrocene-containing cryptands and macrocycles with a range of metal cations (Mn+ = Be2+, Mg2+, Ca2+, Sr2+, Ba2+, Eu3+, Tb3+, Dy3+, Mn2+ and Zn2+) in acetonitrile solutions. Complexation results in a bathochromic shift of the lowest energy ferrocene-centred d-d transitions. Host-guest complexation stoicheiometries have been determined. The stability constants for these equilibria have been evaluated. © 1990.
