Solvent Polarity-Modulated Molecular Alignment of Linear Diacetylenic Acid Films by Solution Shearing
Source abstract
Abstract
Directional alignment of functional molecules has important implications in various areas. Here, films of well-aligned linear diacetylenic acid, 10,12-pentacosadiynoic acid, were prepared by the solution-shearing method and photopolymerized to give well-aligned poly(ene-yne) films. Depending on the polarity of the solvent used in the shearing process, the direction of molecular alignment and the resultant polymer chains varied as a function of the polarity of the solvent used so that they oriented mainly parallel to the shearing direction when a nonpolar solvent was used and mainly perpendicular to the shearing direction when a polar solvent was used. The presence of H-bonded cyclic carboxyl dimers or solvated acid monomers in the solution is suggested to contribute to the different behaviors. Highly anisotropic field-effect mobilities were measured for transistors based on these films as conducting channels, with the highest mobility of 1.63 cm2 V–1 s–1 obtained for films prepared from hexane solution.
