Popis: A layered composites of calix[4]arene, namely, THC4-rGO, was produced from calix[4]arene-25,26,27,28-tetrol (THC4) and reduced graphene oxide (rGO) using the Langmuir–Blodgett (LB) technique. THC4 and rGO were prepared in a solution form first, then by using the LB technique to form LB films which were then deposited onto a quartz surface for Raman and electrical study. Langmuir property such as surface pressure-area (Π-A) isotherms of THC4 and rGO were used to study the intermolecular interactions at air–water interface. Raman spectroscopy was used to observe the crystallinity of the composites. The electrical properties by using four-point probe, i.e., I–V curves, resistivity, and conductivities of the rGO and THC4-rGO were analyzed to illustrate the enhanced properties. The results from this study can be utilized for the potential application of electronic sensors using calix[4]arene.
