报导了一种带5’－CO2Me取代基的螺嗪（A）的开环形式（B）与金属离子的配合作用，利用紫外可见吸收光谱研究了金属离子浓度的影响，并证明了有色体配合物（C）的主要消色过程是先解离出金属离子生成（B）．再褪色生成闭环无色体（A）．未观测到由（C）直接褪色生成（A）的过程·
Reported the complexation of an open-ring form (B) of a spiroazine (A) with a 5’-CO 2 Me substituent with a metal ion. The influence of the metal ion concentration was investigated by UV-visible absorption spectroscopy and it was demonstrated that the colorimetric coordination The main achromatic process of (C) is the dissociation of metal ions (B). Re-fading to generate closed-loop color bodies (A). The process of (A) direct discoloration by (C) was not observed
