摘 要:以帶有取代基的水楊醛和各種帶有取代基團的鄰苯二胺為原料,合成了7種具有熒光性能的苯并咪唑基芳醛化合物。改進(jìn)了實(shí)驗方法,收率提高了20%左右。并使用核磁對產(chǎn)品進(jìn)行了表征,研究其熒光性能。以2-(2-羥基苯基)苯并咪唑為對照,發(fā)現在不同位置引入醛基后熒光均有減弱,其中在苯并咪唑環(huán)上連有醛基使熒光強度明顯減弱。并發(fā)現各種取代基團對苯并咪唑基芳醛化合物的熒光性能均有影響,其中硝基的消光作用明顯。實(shí)驗結果為進(jìn)一步實(shí)驗提供了重要的實(shí)驗依據。 |

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 |
