-isoquinolinium (R-isoQu + ) and -acridinium (R-Ac + ) (R=Me, Et, Pr n , Bu n ) cations were directly intercalated into the α-zirconium phosphate (α-ZrP) interlayer space by redox reactions of their iodide salts. These pyridinium-derivative cations fluoresce intensively even in the α-ZrP interlayer, the fluorescence band being similar to the band observed in solution. The fluorescence decay curves measured for
摘要N-烷基喹啉鎓(R-Qu +),-异喹啉鎓(R-isoQu +)和-ac啶鎓(R-Ac +)(R = Me,Et,Pr n,Bu n)阳离子直接插入α-锆中碘化物盐的氧化还原反应产生的磷酸根(α-ZrP)层间空间。这些吡啶鎓衍生物阳离子甚至在α-ZrP中间层中也发出强烈的荧光,其荧光带类似于在溶液中观察到的带。通过假设双指数模型,合理地拟合了悬浮在乙腈中的插层化合物的荧光衰减曲线。与在乙腈中观察到的那些相比,该化合物包含的阳离子荧光寿命短,这可以解释为由于在层间空间中这些阳离子的高密度而导致的自猝灭。
