By introducing the nano-CaCO3 into in-situ polymerization, a templated material of poly(2,6-diimidazo[4,5-b:4'5'-e]pyridinylene-1,4(2,5-dihydroxy)phenylene)(PIPD) with a narrow pore size distribution can be prepared synchronously. The results we obtained suggested that the nano-CaCO3 played as a nucleation agent during the polymerization, which led to the obvious improvement of formation PIPD nanospheres. The effects of the solvent on the formation of nanospheres have been also investigated. With the treatment of the methanesulfonic acid (MSA), PIPD nanospheres with more regular and ordered morphology were obtained. Pore size distribution of the templated material recorded by mercury intrusion porosimetry (MIP) showed an average pore size with narrow distribution and the porosity of 60.22%.
