Study on monolayer behavior of C60 using BAM and π–A isotherms

The influence of the experimental conditions (concentration, subphase, volume, waiting time, compressing speed and compression–expansion cycle, etc.) and UV-light irradiation on the monolayer behavior of C60 was studied in details by using pressure–area (π–A) isotherms and Brewster angle microscopy (BAM) images. The concentration of spreading solution and the subphase were the most important factors in the formation of relatively homogenous C60 monolayers and Langmuir–Blodgett (LB) films. A concentration of 10−5 M and the phenol subphase were preferred.
