Abstract：
Novel 7,7\'-((anthracene-9,10-diylbis(methylene))bis(oxy))bis(4-methyl-2H-chromen-2-one) (BisCA) was prepared as fluorescent probe. The chemical structure of the novel BisCA was confirmed by spectroscopic data as well as elemental analyses. The solvatochromic characteristics of the new proble and its precursors were investigated in different solvents including, ethanol, DMF and toluene as protic polar, aprotic polar and non-polar solvents, respectively. Photo-physical parameters of probes, such as fluorescence quantum yields, fluorescence lifetime of excited state, radiative and non-radiative decay, were assessed in different media. The intermolecular H-bond effect on absorption and excitation spectra of the novel probe was reported in different solvents. Also, Onsager cavity radius and dipole moment of ground state and excited state of the probe were calculated as described by Bakhshiev and Reichardt methods.
摘要：
制备了新型的7,7'-（（蒽-9,10-二基双（亚甲基））双（氧基））双（4-甲基-2H-色烯-2-酮）（BisCA）作为荧光探针。通过光谱数据以及元素分析证实了新型BisCA的化学结构。研究了新proble及其前体在不同溶剂中的溶剂化变色特性,乙醇,DMF和甲苯作为质子极性，非质子极性和非极性溶剂，分别。探测器的光物理参数，例如荧光量子产率，激发态的荧光寿命，辐射和非辐射衰变，在不同的媒体上进行评估。报道了在不同溶剂中分子间H键对新型探针吸收和激发光谱的影响。此外，如Bakhshiev和Reichardt方法所述，计算了探针的Onsager腔半径和基态和激发态的偶极矩。
