“…This band appears around 1760−1740 cm -1 for a monomeric carboxylic acid. The position of 1706 cm -1 in the present case corresponds to the well-known hydrogen-bonded dimer of carboxylic groups. , Similar absorption of carboxylic acid was also reported for another amphiphilic C60 in the LB films . From these results, it is clear that the monolayer of the C60−AN adduct was transferred on solid substrates without decomposition.…”

A thermal dissociation method was employed to fabricate the Langmuir−Blodgett (LB) films of C60. A C60 adduct with an amphiphilic anthracene bearing a carboxylic group (C60−AN) was synthesized as the precursor molecule. C60−AN formed a monolayer at the air−water interface. The monolayers were transferred on solid substrates to form LB films using a horizontal lifting method. The LB films were subjected to heat treatments and their structural change was investigated by using UV−visible and IR spectroscopies. Most of the C60−AN molecules were dissociated to C60 and amphiphilic anthracenes at 100 °C, followed by the exclusion of the anthracene moiety from the LB films. The thermal dissociation proceeded more at higher temperatures. At 200 °C, the dissociation proceeded completely, although a certain form of hydrocarbon remained in the LB films. All the materials disappeared when the films were heated above 350 °C.

“…38 Monoand Multilayer Experiments. Homolayers were built on a trough patented by Barraud.39 The trough used in the present work for alternate layers was recently described by Barraud et al 40 The subphase was Millipore Q-grade water, unless notice, and all experiments were conducted at 20.22 °C in a nitrogen atmosphere. The solid substrates, which were cleaned by the usual rigorous procedure, were either quartz (for ESR measurements) or calcium fluoride.…”

“…Efforts have recently been directed at depositions with alternating layers of an active dye possessing a strong second-harmonic behavior and an inert layer of spacer molecules, for example, arachidates or stearates. [21][22][23][24][25][26][27][28][29][30] Alternatively, the symmetry can be broken by a head-to-tail deposition (called Z deposition). In addition, there is much to be done concerning the fabrication of thin-film wave guides with the incorporation of molecules having large polarizabilities.…”

The considerable activity in the area of organic thin films, involving very thin polymeric films and molecular monolayers and multilayers, led to the formation of a panel, sponsored by the Materials Sciences Division of the Department of Energy, to review this field. Its purpose was to better understand the relevant scientific topics and to suggest suitable areas of research. In particular, a number of potential applications were identified, which require further scientific advances for them to see fruition. These include nonlinear and active optical devices, chemical, biochemical, and physical sensors, protective layers (e.g., for passivation), patternable materials both for resists and for mass information storage, surface modification (e.g., wetting and electrochemical electrode properties), and synthetic biomacromolecules. Studies of these films have the added advantage that they could lead to a better scientific understanding of such subjects as the relationships between the microstructure of ordered molecular arrays and their collective properties, the tailoring of interfaces and surfaces, especially when used to model multibody interactions, and the physical and chemical reactions of films involving phase transitions and intraand interfilm transport. The areas that appear to require the most attention include the application of new characterization techniques, such as the scanning tunneling microscope, the improvement of mechanical and thermal stability, the identification and characterization of physical and chemical defects, and the effects of internal ordering on macroscopic properties. It is further recommended that strong interdisciplinary efforts be mounted to address and solve these problems.
