Findings from Council of Scientific and Industrial Research (CSIR) Update Understanding of Nanorods (Aligned 1-D Nanorods of a pi-Gelator Exhibit Molecular Orientation and Excitation Energy Transport Different from Entangled Fiber Networks)
By a News Reporter-Staff News Editor at Energy Weekly News -- Researchers detail new data in Nanorods. According to news reporting originating from Trivandrum, India, by VerticalNews correspondents, research stated, "Linear pi-gelators self-assemble into entangled fibers in which the molecules are arranged perpendicular to the fiber long axis. However, orientation of gelator molecules in a direction parallel to the long axes of the one-dimensional (1-D) structures remains challenging."
Our news editors obtained a quote from the research from the Council of Scientific and Industrial Research (CSIR), "Herein we demonstrate that, at the air-water interface, an oligo(p-phenylenevinylene)-derived pi-gelator forms aligned nanorods of 340 +/- 120 nm length and 34 +/- 5 nm width, in which the gelator molecules are reoriented parallel to the long axis of the rods. The orientation change of the molecules results in distinct excited-state properties upon local photoexcitation, as evidenced by near-field scanning optical microscopy."
According to the news editors, the research concluded: "A detailed understanding of the mechanism by which excitation energy migrates through these 1-D molecular assemblies might help in the design of supramolecular structures with improved charge-transport properties."
