In this paper, we report a series of Schiff bases synthesized by the condensation reaction between 2-hydroxy-1-naphthaldehyde with aniline derivatives as well as their further coordination with diphenylborinic acid for giving the corresponding boron Schiff bases (BOSCHIBAs) (E)-N-((2-((di-phenylboryl)oxy)naphthalen-1-yl)methylene)pyridin-3-amine (1a), (E)-N-((2-((di-phenylboryl)oxy)naphthalen-1-yl)methylene)-2
在本文中,我们报告了一系列由2-羟基-1-萘醛与苯胺衍生物的缩合反应合成的席夫碱,以及它们与二苯基硼酸的进一步配位,从而得到相应的席夫碱硼(E)- N-(((2-((二苯基硼基)氧基)萘)(1a),(E)-N-((2-(((二苯基硼基)氧基)萘) -1-基)亚甲基)-2,6-二甲基苯胺(2a)和(E)-N-((2-((二苯基硼基)氧基)萘-1-基)亚甲基)-2,6 -二异丙基苯胺(3a)。所得的BOSCHIBA通过NMR(1 H,13 C和11B),FT-IR和大气压电离飞行时间质谱。BOSCHIBA 1a的结构为单晶。结构分析表明,硼原子采用四面体分子几何结构成具有半椅构象的六元环。BOSCHIBAs 1A -图3a和它们的配体1 - 3在1至3%的范围内表现出相对低的量子产率。在通过使用BOSCHIBAs 2a和3a作为荧光染色染料进行的生物成像研究中,这些材料在低细胞毒性,简单合成,
