Different tris(styryl)benzenes bearing a tert-butyldimethylsilyl (TBDMS) group at the periphery have been efficiently prepared by a straightforward protocol. The potential of these compounds as fluorescent sensors for fluoride has been studied. In all cases, this anion caused significant quenching of the emission intensity upon cleavage of the silyl ether group and the formation of the corresponding phenolate anion. All compounds displayed good selectivity over a variety of other anions. They could sense fluoride ions in aqueous solutions with sensitivity in the lower μM range when dissolved in DMSO, demonstrating the validity of this approach.

甲硅烷基化三（苯乙烯基）苯作为氟化物水溶液潜在荧光传感器的研究

已经通过简单的方案有效地制备了在外围带有叔丁基二甲基甲硅烷基（TBDMS）基团的不同的三（苯乙烯基）苯。已经研究了这些化合物作为氟化物荧光传感器的潜力。在所有情况下，该阴离子在甲硅烷基醚基团裂解时会导致发射强度显着猝灭，并形成相应的酚盐阴离子。所有化合物对多种其他阴离子均显示出良好的选择性。当溶解在DMSO中时，他们可以以较低的μM范围检测水溶液中的氟离子，证明了这种方法的有效性。
