Axial binding and host–guest interactions of a phthalocyanine resorcinarene cavitand hybrid

Abstract

A Zn phthalocyanine–resorcinarene cavitand hybrid was prepared. The axial binding and host–guest interactions of this hybrid with a pyridinyl-pyrene were investigated by UV-vis and fluorescence spectroscopic means, revealing the encapsulation of the guest maintained by axial coordination to the Zn phthalocyanine. Energy transfer between the pyrene and the phthalocyanine was evidenced.
