The studies on discotic molecules at air-water (A-W) and air-solid (A-S) interfaces have drawn lot of attention [1, 2]. The thin films of discotic mesogens have technological applications in the fabrication of gas sensors [3], field-effect transistors [4], photovoltaic diodes [5], solar cells and optical displays [6]. In addition, these systems have scientific interest in modeling of Π-Π and st...
