摘要: A supramolecular hydrogel (defined as G1) formed from 1, 2, 4, 5-benzene tetracarboxylic acid (BTCA) and 2-amino-3-hydroxypyridine possessed higher Tgel than that of another hydrogel (defined as G2) formed from BTCA and 3-hydroxypyridine. Based on the analysis of their xerogels by 1H NMR, IR and XRD, the higher stability of G1 was attributed to the formation of stronger hydrogen binding enhanced by the ortho amino group of 2-amino-3-hydroxypyridine.
