合成了在萘环的 5' 或 9' 位置具有 aza-15-crown-5 醚片段的新型螺萘嗪化合物。光谱动力学测量表明，与碱土金属或稀土金属阳离子络合时发生了两种竞争的形成过程。对所制备的化合物的比较研究证明了分子设计和金属阳离子性质在螺[二氢吲哚-萘嗪]的阳离子依赖性光诱导转化中的作用。
Novel spironaphthoxazine compounds with an aza-15-crown-5 ether fragment at position 5′ or 9′ of the naphthalene ring were synthesised. Spectrokinetic measurements showed the occurrence of two competing formation processes for complexation with alkaline earth or rare earth metal cations. A comparative study of the prepared compounds demonstrated the role of molecular design and the metal cation nature in the cation-dependent photoinduced transformation of spiro[indoline-naphthoxazines].
