摘要
A novel photochromic Schiff base derivatives carrying a calix[4]arene group have been synthesized through incorporating two imine groups Into the upper rim of a calix[4]arene The addition of dysprosium(III) ion (Dy3+) to the Schiff base compound resulted in the solution color change from colorless to yellow No color change was observed in the solution of model compoud without calix[4]arene cavity upon addition of Dy3+ It indicates that the synthetic receptor can effectively recognize Dy3+ ion by naked eyes over other cations The chemosensor can be applied in analytical chemistry for detection of Dy3+ ions
