4'- biphenyldicarboxaldehyde as organic monomers was well designed and successfully synthesized based on the principle of Schiff-base reaction and the covalent bond as cross-linking point. The synthetic method of AB-gel has the characteristics of simple
mild condition
no catalyst
fast reaction rate and high yield. The structure and properties of the materials were characterized by infrared spectroscopy
13
C solid state NMR
scanning electron microscopy
X-ray powder diffraction and thermogravimetric analysis. The results show that the AB-gel material has uniform nanoparticle size
porous three- dimensional net-work structure and excellent physical and chemical properties.
