Abstract:
The metal binding properties of macrocyclic small molecules is a key property that drives what applications for which these ligands can be used. Pyridine modified Py2N2 pyridinophane small molecules are a new class of macrocyclic small molecules, whose properties have not been explored. As a result, Zn(II) metal binding of a library of six pyridine modified Py2N2 complexes are reported here. These results include 1H NMR, log βZn(II), and X-ray diffraction, which are compared to PyN3 congeners to show that the differences in each scaffold yield markedly different metal binding properties that can be exploited in future applications.
