Sulfoxides are shown to be viable reporting groups for fluorescent chemosensor development. Metal coordination of sulfoxide-appended fluorophores suppresses excited-state pyramidal inversion of the sulfoxide, leading to enhanced fluorescence emission. This new structural motif allows the construction of fluorescent chemosensors that do not require nitrogen coordination as part of the signaling process
亚砜被证明是荧光化学传感器开发的可行报告组。亚砜附加荧光团的金属配位抑制亚砜的激发态锥体反转,导致荧光发射增强。这种新的结构基序允许构建不需要氮配位作为信号传递过程的一部分的荧光化学传感器,该传感器对亲氧金属离子具有一系列选择性和亲和力,并且可以在水中发挥作用。
