Syntheses, Structures, and Properties of Three New Polymers Based on Flexible and Rigid Ligands

Three new supramolecular polymers, [(IP)(H2SO4)(H2O)] (1), [(H2SDC)(BPA)] (2) and [Mn(SDC)(IP)(2)](n) (3), have been constructed by three modes (rigid IP, rigid SDC + flexible BPA, rigid IP + rigid SDC). Polymers 1 and 2 are supramolecular structures, assembled by hydrogen bonds and pi center dot center dot center dot pi interactions. X-ray structure analysis of 3 shows waved 1D chains which form a 3D supramolecular network by hydrogen bonds and pi center dot center dot center dot pi interactions. Solid-state properties of thermal stability, luminescent properties, and X-ray powder diffractions for these crystalline materials have also been investigated, and polymer 3 is considered to be a good stable luminescence material.
