摘要
4,5-二氮杂芴-9-酮与苯肼/对硝基苯肼在酸性条件下通过缩合反应合成了2个未见报道的新型席夫碱4,5-二氮杂芴-9-苯腙(DAFPD)和4,5-二氮杂芴-9-对硝基苯腙(DAFND)并得到其晶体。通过红外光谱、元素分析和单晶X-射线衍射等对两化合物进行了表征。实验发现,DAFND具有而DAFPD不具有热致变色和溶致变色性质。采用电子吸收光谱法,通过与常见过渡金属离子作用,发现DAFPD对Co2+和Fe3+有识别作用,而DAFND能够特异性识别Fe3+和Cd2+。
Two novel schiff bases of phenylhydrazone were synthesized by the condensstion reaction between 4,5-diazafluo- rene-9-one and phenylhydrazine/4-nitrophenylhydrazine in acidic condition. The compounds were characterized by IR, elemental analyses and single-crystal X-ray diffraction. The results reveal that DAFND have thermochromism and solvatochromism. Fe^3＋ can be specifically recognized by both compounds by UV-vis spectra, and Co^2＋ and Cd^2＋ obviously interacted with DAFPD and DAFND at the .same conditions, respectively.
