Abstract
- Summary of main observation and conclusion: 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. [ABSTRACT FROM AUTHOR]
