Crystalline structure, molecular motion and photocarrier formation in thin films of monodisperse poly(3-hexylthiophene) with various molecular weights

A better understanding of the carrier formation process for semiconducting polymers, especially in thin films, is essential for designing and constructing highly-functionalized polymeric optoelectronic devices. We herein examined effects of the crystalline structure and thermal molecular motion on photo-carrier formation for melt-crystalized thin films of monodisperse poly(3-hexylthiophene) (P3HT) with various molecular weights (MWs), which were prepared from polydisperse sample by preparative chromatography.

Smectic ordered structure and water repellency of a poly(fluoroalkyl acrylate) with a carbamate linker

Thermal behavior, molecular aggregation structure, and water repellency of a comb-shaped fluoropolymer, poly{2-[(perfluorooctylethyl)carbamate]ethyl}acrylate (PFAUr-C₈), were investigated. PFAUr-C₈ exhibited polymorphic ordered structures, where the stacked lamellar structure of R_f side chains was maintained without their lateral translational order. The cohesive dipolar interactions in the carbamate linkers would induce the thermal stability of the lamellar structure. PFAUr-C₈ exhibits superior water repellency.
