Effect of different temperature on the N-[(3-pyridine)-sulfonyl]aspartate polymers synthesis: Crystal structure and fluorescence

Abstract

The title coordination polymers of Zn(II), Cd(II), Pb(II) based on H₂L (H₂L = N-[(3-pyridine)-sulfonyl]aspartate) had been synthesized in the same material ratio, under different synthesis temperature. The results show that the polymer 1 is a three-dimensional structure and synthesized under room temperature condition; the polymers 2–4 are two-dimensional structure and synthesized under hydrothermal synthesis conditions. A structural comparison of these polymers suggests that different reaction temperatures play important role in the construction of resulting architectures for 1–4. Fluorescence properties of these polymers showed blue shift occurred.
