Abstract

The emission intensities of a fluorescent monomer–aggregate coupled system, based on 7-(dimethylamino)-coumarin-3-carbaldehyde, exhibit ultra-low temperature dependence with a low temperature coefficient of only 0.05% per °C, by judicious selection of the excitation wavelength. This finding has significant implications to temperature-sensitive fluorescent applications.
