本论文以硼酸、苯硼酸、间氟苯硼酸为母体，采用微波法合成了一系列含N→B键的杂环荧光化合物，并对此类化合物进行了红外、紫外、荧光、元素分析、XRD等表征。微波法与传统的溶液法相比具有快速、高效、受热均匀等特点，本论文经过一系列的条件实验获得了微波法合成的最佳条件，并在此条件下大量快速高效的合成了上述化合物。 化合物1是以水杨醛、正丙胺、硼酸为原料在乙腈中合成的，该反应采用一锅法，在合适的微波条件下短时间大量合成了此化合物，其在紫外光照射下，有蓝色荧光产生。 化合物7、8是以水杨醛、乙醇胺、苯硼酸或间氟苯硼酸为原料在乙腈中合成的化合物，该反应采用一锅法，在合适的微波条件下短时间大量合成了此化合物，并采用溶液扩散法得到了化合物7、8的晶体，对晶体结构进行了测定，同时也做了离子识别研究，结果表明含氟的双核醇胺类硼酸酯对一价离子有很好的识别作用。 近年来，以往的硼酸发光化合物只能对糖类、多元醇等含多个络合基团的底物进行手识别，而不能对阴阳离子进行识别，而离子的识别具有重要的意义。因此对所合成的硼酸酯进行了离子识别研究。 |

This article introduces microwave synthesis of a serial N→B bond containing heterocyclic fluorescent compounds from boric acid, tetraphenylborate and fluorophenyl borate. IR, UV, fluorescence, element analysis, XRD was performed to characterize those compounds. Compared with traditional solution method, microwave method is quicker, more efficient and evenly heated. Optimum conditions of microwave synthesis are obtained after rounds of variable experiments, in which the above mentioned compounds were synthesized massively and efficiently. Under appropriate microwave conditions, compound 1, with salicylaldehyde, propylamine, boric acid as substrates, was synthesized massively through one-pot method in acetonitrile. In UV irradiation blue fluorescence generates. Under appropriate microwave conditions, compound 7 and 8, with salicylaldehyde, ethanolamine, benzene boric acid or boric acid fluorophenyl as substrates, were synthesized massively through one-pot method in acetonitrile. With solution diffusion method compound 7 and 8 were crystallized, whose crystal structure were characterized, and ion discern was researched, which indicates good discern of one valence ion by fluorine containing dual-core alcohol amine borate. In recent years, previous light-emitting borate compound only discern substrates with many complex group, for example, carbohydrate and polyols, instead of ions discern, which are of great importance. So ion discern of borate esters were performed. |
