摘 要:以带有取代基的水杨醛和各种带有取代基团的邻苯二胺为原料,合成了7种具有荧光性能的苯并咪唑基芳醛化合物。改进了实验方法,收率提高了20%左右。并使用核磁对产品进行了表征,研究其荧光性能。以2-(2-羟基苯基)苯并咪唑为对照,发现在不同位置引入醛基后荧光均有减弱,其中在苯并咪唑环上连有醛基使荧光强度明显减弱。并发现各种取代基团对苯并咪唑基芳醛化合物的荧光性能均有影响,其中硝基的消光作用明显。实验结果为进一步实验提供了重要的实验依据。 |

Abstract:Seven benzimidazole aryl aldehydes with fluorescent properties were synthesized from substituted salicylaldehydes and substituted o-phenylenediamines by improved technology with yield increase of 20%,and their fluorescent properties were studied. Comparing with 2-(2-hydroxyphenyl)benzimidazole,it was found that the fluorescence intensity was decreased with an aldehyde group on the molecule,especially on the benzimidazole moiety. In addition,a variety of other substituents,for example nitro group,on benzimidazole aryl aldehydes were found to induce the decrease of the fluorescent properties. Further investigations are in progress. |
Key words:benzimidazole;fluorescent properties;aryl aldehyde compound |
