Tj = 470 K). Sorai and Seki62 63) proposed more recently the term glassy liquid crystal. They based their analysis on a more detailed thermodynamic study.

Even with all of its sophistication, the mode coupling theory is still a perturbation theory where dynamics is described in terms of a subset of dynamical variables chosen from the products of hydrodynamic modes. It fails, for example, to describe rare events, such as the activated processes or stringlike cooperative motions often found to dictate dynamics in glassy liquids [13-15].

Using the same strategy, photoresponsive glassy liquid crystals were also obtained using dithienylethene moieties [327]. 

The rheological properties of glassy liquids are dominated by one or more very long relaxation times and a high modulus. The detailed linear viscoelastic response varies somewhat with the type of liquid. Some inorganic glassy liquids, such as zinc alkali...
