摘　　要：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 Kwith a high theromosensitivity.In comparison,model compounds with one or two triarylamine arms show distinctly lower thermosensitivity.
