合成和表征了两种新的有机碲烷分子簇，包括一个无机Te 8 O 6X 4（X = Cl，Br）的核心结构。高度吸电子的3，5-双-三氟甲基苯基基团的组成Te（IV）中心的整合被确定为是至关重要的硫族元素键合（ChB）卤化物模板定向组装。通过多核H-1、Te-125、F-19 NMR、UV-Vis、IR光谱和X射线晶体结构分析，证明该分子簇具有良好的有机溶剂溶解性和化学稳定性。此外，初步的荧光研究表明，碲氧烷在有机水溶剂混合物中表现出聚集诱导发射（AIE）行为。
The synthesis and characterisation of two novel molecular organotelluroxane clusters, comprising of an inorganic Te8O6X4 (X = Cl, Br) core structure are described. The integration of highly electron withdrawing 3,5-bis-trifluoromethylphenyl groups to the constituent Te(iv) centres is determined to be crucial in the chalcogen bonding (ChB) halide template directed assembly. Characterised by multi-nuclear H-1, Te-125, F-19 NMR, UV-Vis, IR spectroscopies and X-ray crystal structure analysis, the discrete molecular clusters exhibit excellent organic solvent solubility and remarkable chemical stability. Furthermore, preliminary fluorescence investigations reveal the telluroxanes exhibit aggregation induced emission (AIE) behaviour in organic aqueous solvent mixtures.
