ASE quaternization reaction is used as reactivity probe within Sm B solvents. The aim of the present study was that of investigating, by means of many physical techniques (DSC calorimetry, Optical Microscopy, X-ray diffraction. Kinetic measurements and Linear Dichroism), the profound differences which occur in a reaction carried out in “internally non- homogeneous” smectic phases with respect to “internally homogeneous” media, such as ...
