Preparation and photoluminescence properties of functionalized silica materialsincorporating europium complexes

摘要

In the present work, the surface of the Eu-BTC = [Eu(EMA)(H_2O_)2], [Eu(TLA)(H_2O)_4l and |Eu(TMA)(H_2O)_5] complexes (EMA = 1,2,3-benzenetricarboxylate, TLA = 1,2,4-benzenetricarboxylate and TMA = 1,3,5-ben-zenetricarboxylate) was modified using 3-aminopropyltriethoxysilane (APTES) by a new microwave assisted method that proved to be simple and efficient. According to our observations, the most efficient luminescence is the material based on APTES incorporating [Eu(TMA)(H_2O)_6] complexes, denoted as Eu-TMA-Si, shows the highest emission efficiency. Therefore, it is proposed as a promising material for molecular conjugation in clinical diagnosis.
