Loaded nanomicellar structures in water with potentional application in cosmetics such as sun protection and care of sunburn were developed on establishing chemical experiments for teaching without requiring hazardous chemicals, however, concerning an actual field of research. Such micellar systems in water may form „nano laboratories“, for example for the application of lipophilic substances in water. This is demonstrated for fluorescent dyes and lipophilic pH indicators. Finally, supramolecular functional units were stabilized in such structures inducing their operation by interaction. Such micelles may be variously applied in chemical didactics beginning from tests for demonstration, and moreover, for basic and advanced chemical education of students. 相似文献

The 1,3‐Dimethylcyanurate Ion as an Ambident Ligand 1,3‐Dimethyl‐2,4,6‐trioxo‐1,3,5‐triazin ( 7 ), (1,3‐dimethylcyanuric acid, DMCH), obtained from the thermolysis of methyl urea, is deprotonated with lithium ethylate. In the resulting dinuclear complex [(DMCLi)2·4 H2O] ( 8 ), the heterocyclic anions are linked to the lithium centres with oxygen atoms as its enolate form. In the corresponding silver complex [(DMCAg)2·en] ( 10 ), (en = ethylendiamine), N‐coordination of the ligand is observed. The crystal structures of 7 , 8 , and 10 reveal the presence of intermolecular hydrogen bonds. 相似文献
