lux on alcohols: Molecular‐level resolution was achieved for the detection of short‐chain alcohols in the vapor phase using a fluorescent cavitand sensor. The transduction mechanism, activated exclusively by the complexation mode, is provided by the change of the electronic density on the fluorophore caused by the formation of an intracavity hydrogen bond between the cavitand PO and the alcohol OH group
酒精上的菲亚特勒克斯(Fiat lux):使用荧光空泡传感器在气相中检测短链醇类时达到了分子级分辨率。唯一通过络合模式激活的转导机制是由荧光体上电子密度的变化所引起的,该电子密度的变化是由于空泡体PO与醇OH基团之间形成腔内氢键而引起的。
