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
具有两个芘部分的新型 podand 型氟离子载体:2,2'-双(1-芘乙酰氧基)二苯硫醚 (3)、2,2'-双(1-芘乙酰氧基)二苯亚砜 (4) 和 2,2'-双(1-芘基乙酰氧基)二苯基砜 (5) 是通过将两个 1-芘羰基甲基与 2,2'-二羟基二苯基硫醚、亚砜和砜的两个羟基连接起来而合成的。通过荧光光谱检查它们对碱金属离子的络合行为。在这些氟离子载体中,具有亚磺酰基的化合物 4 对 Li+ 显示出高选择性。
