Abstract
Ultrathin films have become an important advancement in modern society with many diverse applications, including solar cell parts, computer chips, and anti-reflective coatings on glasses. The Langmuir-Blodgett (LB) technique was employed to deposit ultrathin films on substrates. Intermolecular forces strongly influence the formation or these films, and our studies of the formation and properties of such films help us understand these forces. The method exploits the hydrophilic and hydrophobic properties of an amphiphilic molecule to develop film at the air-water interface. Pressure vs area isotherms were taken to characterize the gas-like, liquid-like, and solid-like phases and to determine the zero-pressure molecular area for optimal film deposition. A substrate is dipped into the water to deposit a single molecule layer film. Multiple layered films are deposited by passing the substrate through the air-water interlace multiple times. Small molecule fluorophores (SMF's) are small molecules that emit light from an excited state. They ere added as dopants to the LB film. Trapping the fluorophores into the LB film reduces the degrees of motion available to the molecule. This is likely to influence the fluorescence time, which ls measured by time-resolved fluorescence.
