[reaction: see text] The fluorescent photoinduced electron transfer (PET) chemosensors 2 and 3 were designed for the recognition of anions possessing two binding sides such as dicarboxylates and pyrophosphate; the anion recognition in DMSO takes place through the two charge neutral thiourea receptor sites with concomitant PET quenching of the anthracene moiety. The anion binding of acetate, phosphate, and pyrophosphate to 2 and 3 was also evaluated by using 1H NMR in DMSO-d6.
[反应：见正文] 荧光光诱导电子转移（PET）化学传感器2和3被设计用于识别具有两个结合位点的阴离子，如二羧酸盐和焦磷酸盐；在二甲亚砜（DMSO）中的阴离子识别通过两个电荷中性的硫脲受体位点进行，同时伴随着蒽部分的PET猝灭。还通过在氘代二甲亚砜（DMSO-d6）中使用1H NMR评估了乙酸盐、磷酸盐和焦磷酸盐与2和3的阴离子结合情况。
