  • Abstract
    Structural evolution with temperature of tetraphenylethene (TPE) is followed using THz-TDS. The observed changes in the terahertz spectra are rationalized by performing DFT calculations on experimentally determined low and high temperature crystal structures, thus allowing the changes to be rationalized in terms of the subtle changes in the supramolecular structure.
