摘 要：2,6-bis(2-benzimidazyl)pyridine ligand(L)with or without suqaric acid in the presence of Zn(II)and Ni(II)has been found to form gel-like materials(GLs).The GLs have been characterized by IR,optical microscopy,SEM and *** the chemical stimuli,rheology study and dye absorption monitored by UV-vis have been done to investigate the properties of the *** results show that L with Zn(II)was found to gelate DMF to generate weak metal-organic gels(MOGs),while adding suqaric acid in the above system can form MOGs with higher mechanical strength and *** shape samples observed in optical microscopy turned out to be different morphologies in SEM and TEM *** structures formed by strands and fibers had better machinery and dye absorption properties than those of networks formed by fibers and *** dye absorption amounts are in the range of 12.15-15.38 *** synergetic effect of the coordination and hydrogen bonding in the samples is the key factor to form *** the probable assembly of the ligand,squaric acid and metal ions to form gel has been proposed.
