以三氟苯乙酮的可逆水化反应为基础，构建了一种新型湿度传感器。由于这种水合作用之后，苯乙酮的吸收光谱发生了变化，因此在紫外范围内进行直接的光学转导是可能的。将这种电中性和亲脂性化合物与季铵盐（MTDDACI）作为催化剂结合在一起的塑化聚氯乙烯（PVC）膜表现出一系列令人印象深刻的特性。利用两种等离体配体，可以高精度地测定1% ~ 100% RH范围内的相对湿度
The reversible hydration of trifluoroacetophenones was taken as the basis for the construction of a new kind of humidity sensor. Since this hydration is followed by a change in the absorption spectrum of the acetophenone isologues, a straightforward optical transduction in the UV range was possible. Plasticized poly(vinyl chloride) (PVC) membranes that incorporate such electrically neutral and lipophilic compounds together with a quaternary ammonium salt (MTDDACI) as a catalyst exhibit a series of impressive characteristics. With two isologue ligands, a determination of relative humidity (RH) in the range from 1% to 100% RH with a high precision was possible
