摘要：

Halochromic Molecules. Synthesis and Acidobasic Behaviour of Substituted 3′,6′‐Bis(dimethylamino)‐spiro [5H‐imidazo [2,1‐α]isoindolin‐5,9′‐xanthenes] Substituted 3′,6′‐Bis (dimethylamino)‐spiro [5H‐imidazo [2, 1‐α]isoindolin‐5,9′‐xanthenes] are prepared and their 1H‐NMR. spectra are discussed. An investigation of the complex protonation equilibria is made by stopped flow kinetic and spectrophotometric methods. pK values are determined and the results are discussed.
