Formation and characterization of organogels showing a red emission triggered by complexation.

在这项研究中，已经完成了由络合引起的具有强烈红色发射的有机凝胶的形成。我们已经制备了具有尿素单元的配体然后这些配体与铕金属络合。我们发现，根据溶剂的不同，配合物可以形成具有强红色发射的有机凝胶。具有两个长烷基链的配体表现出胶凝能力及其配合物。有趣的是，具有三个长烷基链的配体即使在配位后也表现出弱的胶凝能力。

In this research formation of organogels showing a strong red emission triggered by complexation has been done. We have prepared the ligands having the urea units and then complexed these ligands with a europium metal. We have found out that the complexes can form the organogels exhibiting a strong red emission depending solvents used. The ligands having two long alkyl chains show the gelation ability as well as their complexes. Interestingly the ligands having three long alkyl chains show weak gelation ability even after complexation.
