STUDIES REGARDING AUTOASSEMBLY PROPERTIES OF SOME BOLAAMPHIPHILES MATERIALS
The study presented the synthesis of four bolaamphiphilic materials, two of cyclic symmetrical tetraester type (TATB) and 2,5,18,21-tetraoxo-1,6,17,22-tetraoxacicloditriacontan- 3,19(20) bis (b-D glucopiranozil-tio tetraacetate) (TGTB) and two of diacid diester type: bis (triethanolamine 2-butenedicarboxylate) 1,10 decanediyl ester (TEADB) and bis <2-butyl (bis- sodium thioacetate) dicarboxylate> 1,10 decanediyl ester (TADB). The obtained materials present self assembling properties. Vesicles were identified by electronic microscopy (TEM) for studied bolaamphiphiles. The aggregation critical concentrations were determinated by UV-VIS spectroscopy.
