New podand-type fluoroionophores having two pyrene moieties: 2,2´-bis(1-pyrenylacetyloxy)diphenyl sulfide (3), 2,2´-bis(1-pyrenylacetyloxy)diphenyl sulfoxide (4), and 2,2´-bis(1-pyrenylacetyloxy)diphenyl sulfone (5), have been synthesized by connecting two 1-pyrenecarbonylmethyl groups with the two hydroxy groups of 2,2´-dihydroxydiphenyl sulfide, sulfoxide, and sulfone, respectively. Their complexation behavior toward alkali metal ions was examined by fluorescence spectroscopy. Among these fluoroionophores, compound 4, having a sulfinyl group, showed high selectivity toward Li⁺.
具有两个芘基部分的新型荚状型荧光离子载体
2,2′-双（1-芘基乙酰氧基）二苯硫醚（3）、2,2′-双（1-芘基乙酰氧基）二苯亚砜（4）和 2,2′-双（1-芘基乙酰氧基）二苯砜（5），是通过将两个 1-芘羰基甲基基团与 2,2′-二羟基二苯硫醚、亚砜和砜的两个羟基分别连接而合成的。通过荧光光谱法研究了它们对碱金属离子的络合行为。在这些荧光离子载体中，具有亚磺酰基的化合物 4 对 Li⁺具有高选择性。
