Abstract
The stability of Langmuir films of [60]fullerene bisphenols 1-3, monophenol s 4 and 5, and monocateohol 6 was investigated on the basis of surface pres sure-area (pi-A) isotherms. The films of 1-3 were found to be more stable t han those of 4-6. Among bisphenols 1-3, cis-3-isomer 2 forms less stable La ngmuir films than cis-2- (1) or e-isomer (3). This is ascribable to the low er hydrophilicity due to the intramolecular hydrogen bonding between the OH groups in 2, as demonstrated by the H-1 NMR and IR spectroscopies. The con tribution of intramolecular hydrogen bonding was also observed in monocatec hol 6.
