摘要

Compounds exhibiting tunable fluorescence emission upon adjusting the temperature are considered smart materials. Herein a three-dimensional structure of {[Cd(TBAPy)(H2O)(2)]center dot 4(H2O)}(n) (1) constructed from Cd-II and 1,3,6,8-tetrakis(4-carboxylphenyl)pyrene (TBAPy(4-)) ligand was synthesized and characterized. Temperature-dependent fluorescence studies showed the emission intensities for compound 1 decrease as temperature increasing. The emission intensity is linearly related to temperature in the range of 100 to 300 K. This findings demonstrate that compound 1 is a good candidate for temperature sensitive sensor over a wide temperature range. Such a fluorescence behavior is closely related to the highly conjugated organic ligand with a pyrene core.
