In this study, we synthesized a visible-light active titanium-oxo cluster (TOC), [(CH3)2NH2]+2·[Ti4L2(OiPr)10]2- (1, H4L= Ellagic acid) based on ellagic acid. The molecular structure of 1 was determined using single-crystal X-ray diffraction, revealing cyclodextrin-like (CD-like) tetramer formed by four (Ti4) clusters and dimethylamine cations. Due to effective ligand-to-metal charge transfer (LMCT), exhibited good visible light absorption photocurrent response, as confirmed UV-Vis spectroscopy photoelectric testing. Structurally, the large number uncoordinated oxygen sites in can be used not only assembly but also for NO2 detection. Moreover, exhibit high response excellent selectivity under irradiation at room temperature. This research marks first exploration TOCs gas sensing applications, expanding its potential beyond traditional uses.
