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 (pi-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-Vcurves, 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.
