Temperature-sensitive functional molecules
 Spasovová, Monika ; Hanyková, Lenka (advisor) ; Starovoytova, Larisa (referee)
The object of our study is a phase separation of porphyrin derivative PNIPAm-TPP. This molecule combines the properties of temperature-responsive polymers with those of well- defined small organic molecules. It is one of the few small organic molecule which shows temperature responsive behavior. We studied its phase separation using high resolution NMR spectroscopy and optical microscope. We applied Flory-Huggins theory to experimental data gained from VT (variable temperature) experiments and we obtained a phase diagram with spinodal and binodal curve. We also obtained LCST (lower critical solution temperature) of the solution and its critical concentration.
