Self-assembly of two New Zinc coordination Polymers Based on N-[(3-Pyridine)-sulfonyl]amino Acid: Structure and Fluorescence

Abstract

Two new zinc coordination polymers based on N-[(3-Pyridine)-sulfonyl]amino acid ligand have been synthesized and characterized by single-crystal X-ray diffraction and elemental analysis. The results show that the 1 is a two-dimensional structure polymer and synthesized under room temperature condition; the 2 is a three-dimensional structure polymer and synthesized under hydrothermal synthesis conditions. These two structures are formed by 4,4'-dipyridy and 4,4'-azpy for 1 and 2 , respectively. A structural comparison of these two polymers suggests that different reaction temperatures play important role in the construction of resulting architectures for 1 and 2 . Fluorescence measurements show that 1 has medium fluorescent emission at 374 nm and 2 has medium fluorescent emission at 438 nm.
