Herein, a self-assembly system with polymer pattern of lower molecular weight polyaerylie acid have been built up, in which some nanosized complex was synthesized, including nanosphere of Pb-PAA, one-dimensional nanorod of CuS-PAA and PbS-PAA, one-dimensional helix nanochain of PbSO4-PAA, and one-dimensional reticulate nanofibres of PbCr2O7-PAA. The mechanism was discussed preliminarily, the important action of the bone angle torsion as well as the ""contact bridge"" served by ion in the course of self-assembly was proposed for the first time.
