| 摘 要： | 以2-羟基-1-萘甲醛和2-羟甲基冠醚为原料,合成3种新的含萘并呋喃基团冠醚(3a-3c),并经1 H NMR,13C NMR,MS及元素分析确证.碱金属和碱土金属离子的加入对体系的最大吸收波长影响不大.Li+使3b摩尔吸光度变大,Ca2+和Ba2+引起3a-3c最大发射波长λem发生相对较大红移,同时使其荧光强度降低.

| Abstract: | Three novel crown ethers containing naphthofuran moiety(3a-3c) were synthesized from 2-hydroxy-1-naphthaldehyde and 2-hydroxymethyl crown ethers,and characterized by 1H NMR,13C NMR,MS and elemental analysis.In acetonitrile,the addition of alkali and alkali earth metal ions showed little effect on the maximum absorption wavelength of 3a-3c.Li+ increased the molar absorbance of 3b.Ca2+,Ba2+ caused the maximum emission wavelengh λem of 3a-3c relatively large red shift,and decreased their fluorescence intensity. |
