| 摘 要： | Six new multidentates, chromogenic squaraine ligands, 3 ～8 are synthesized. In butanol-toluene couple medium, o-aminophenol reacts with squaric acid to give 1, 3-bissubstituted product 2 and monosubstituted product 3. It is noteworthy that reactions of N- hydroxyethyl-(2-amino-4-chloro) aniline and N-hydroxyethyl-(4-chloro-2- nitro) aniline with squaric acid do not give isosquaramide, 1, 3- substituted derivate but squaramide, 3, 4-substituted derivates 7 and 8.
