摘要

Cu~(2+) is an eminent trace metal ion in the human body as a structural cofactor that can enhance immune function. Aluminum is one of the most abundant elements found in the earth's crust and most biological tissues appear in Al~(3+) form. Hg~(2+) is probable to cause cancer with high toxicity. However, excess accumulation of Al~(3+), Cu~(2+) or Hg~(2+) in the body leads to many diseases. Therefore, detecting the level of Al~(3+), Cu~(2+) and Hg~(2+) are very important for human health. However, preparing a suitable single probe for the simultaneous detection of Al~(3+), Cu~(2+) and Hg~(2+) remains a challenge. TPE-based carbohydrazide derivative (TPE-Ch) was synthesized by the one-pot reaction. The TPE-Ch displayed notable AIE and AIEE phenomena and can act as a fluorescence sensor that turns on toward Al~(3+) in ethanol/water mixtures (f_w = 70%) and turns off toward Cu~(2+) or Hg~(2+). TPE-Ch can produce various assemblies by coordination with Al~(3+), Cu~(2+) and Hg~(2+), including nanospheres, tree-like assembly morphology and belt-like superstructures. Optical microscopy (OM), scanning electron microscopy (SEM), X-ray diffraction (XRD), and fluorescence spectrography were employed to characterize the self-assemblies.
