Luminescence thermometry has attracted more and more attention due to its non-contact and noninvasive operation, fast response, high spatial resolution, and so on, for which the luminescent thermometers are the key. Here, a 1D complex [Tb4(HTC4A)(TC4A)(OBBA)2(CH3OH)4(μ4-OH)]n (1) was obtained by solvothermal synthesis, where H4TC4A=p-tert-butylthiacalix[4]arene, and H2OBBA=4, 4′-oxybisbenzoic acid. This complex is featured with a chain-like polymer constructed by bridging some sandwich-like Tb4-(TC4A)2 entities through OBBA2- ligands. It exhibited the characteristic emission of the Tb3+ ion. Both fluorescence intensity and lifetime decreased with increasing temperature. The relative sensitivity was up to 8.743%·K-1 at 473 K, indicating it is a good ratiometric luminescent thermometer. This complex had good stability under different pH values and in common solvents.
