The equilibrium geometry of cyclic dimer of zinc porphyrin containing Qb has been studied by semi-empirical AMI and PM3 methods. The electronic spectrum and the third-order nonlinear polarizability of this supramolecule were examined by ZINDO-SOS method. At different external field frequencies, the range of calculated third-order nonlinear polarizability is from 48.23 * 10~(-34) to 65.15 * 10~(-34) esu. The supramolecule would potentially be employed as a kind of nonlinear optical material.
