Bi. Seo et al., IN-SITU STUDYING OF C-60 LANGMUIR-BLODGETT-FILMS DEPOSITED ON A QUARTZ-CRYSTAL MICROBALANCE, Synthetic metals, 86(1-3), 1997, pp. 2423-2424
Buckminsterfullerene(C-60) has been investigated at the air-water inte
rface using Langmuir trough. Surface pressure-Area(pi-A) isotherm show
ed differing properties. Particularly, the area/molecule of C-60 was m
ore diminished than expected. Quartz crystal microbalance(QCM) was app
lied to in-situ weighing of Langmuir-Blodgett(LB) films transferred fr
om water surface, and suggested that C-60 film does not exist in the f
orm of a monolayer at the air-water interface. In-situ weighing could
also examine the extent of multilayer formation of C-60 molecules at t
he air-water interface.
