摘要: Herein, we present the results obtained from our studies on supramolecular self-assembly and molecular mobility of low-molecular-weight gelators (LMWGs) in organic solvents using pulsed field gradient (PFG) diffusion ordered spectroscopy (DOSY) NMR. A series concentration-dependent DOSY NMR experiments were performed selected LMWGs to determine critical gelation concentration (CGC) as well understand behaviour gelator molecules gel state. In addition, variable-temperature gel-to-sol transition. The PFG a function strength further analyzed monoexponential processing, compared with automated Bayesian transformation obtain 2D plots. Our provide useful information stepwise small leading gelation. We believe that these are applicable determining CGC melting temperatures gels.
