Abstract
The interaction of (L)-lactic acid with p-tert-butylthiacalix[4]arene containing ethoxycarbonyl fragments in the 1,3-alternate conformation was studied in tetraglyme. For the first time, the lactic acid oligomer was obtained by polycondensation with the macrocycle and characterized by 1H, 13C NMR, IR spectroscopy, MALDI mass spectrometry and gel permeation chromatography. Thermal stability of the obtained copolyester of lactic acid and thiacalix[4]arene was studied by TG/DSC analysis and the effect of the macrocyclic platform on its thermal properties was shown. Copolyester obtained was thermally more stable than oligolactic acid. Self-assembly of synthesized oligomer was studied by dynamic light scattering method. It was shown that monodisperse particles (PDI = 0.13) with the size of 208 ± 4 nm are formed in CH3CN solution at 2.5 × 10−5 M concentration.
