A star‐shaped compound 1 with a pyrene core and four triarylamine arms has been prepared and characterized. It exhibits intense intramolecular‐charge‐transfer (ICT) emissions with strong solvatofluorochromism. On the basis of the temperature‐dependent emission color and wavelength changes, compound 1 behaves as a fluorescent thermometer between 200 and 400 K with a high theromosensitivity. In comparison, model compounds with one or two triarylamine arms show distinctly lower thermosensitivity.

在宽温度范围内星型溶剂荧光变色P-三芳基胺衍生物作为荧光温度计†

制备并表征了具有a核和四个三芳基胺臂的星形化合物1。它表现出强烈的分子内电荷转移（ICT）发射和强烈的溶剂化荧光色。根据与温度有关的发射颜色和波长变化，化合物1表现为200至400 K之间的荧光温度计，具有较高的热敏性。相比之下，具有一个或两个三芳基胺臂的模型化合物显示出明显较低的热敏性。
