Study of molecular arrangement of organized molecular films of charge–transfer complexes containing 1,3-dithiole-2-thione-4,5-dithiolate by in-plane and out-of-plane X-ray diffractions

Morphological transition of a conductive molecular organization with non-covalent from nanonetwork to nanofiber

“…The short spacing value of 4.1 Å appears to correspond to the stacking of the TTF molecular planes based on p-p interactions. A similar in-plane packing system based on p-p interactions, established by in-plane XRD, was reported in conducting organized molecular films of metal (dmit) 2 charge transfer complexes [38]. Dense stacking of molecular planes has been known to induce electrical conductivity along the direction of stacking [39].…”

Epitaxial Growth of Conductive Charge-transfer Complex in the Organized Molecular Film on Fluorinated Copolymer as Template

“…The a few layer level resolution of this in-plane XRD apparatus was realized by applying the X-rays at an incident angle of 0.2° and by slow scanning at 0.05°/50 s. Figure 1 shows schematic packing models of didodecylammonium-Au(dmit) 2 (2C10-Au(dmit) 2 ), which indicate excellent conductive properties, 16 in the single crystal.…”

“…14,15 In a previous study, we have investigated molecular arrangement of organized molecular films of several alkylammonium-metal(dmit) 2 complexes and relationships between their arrangements and conductive properties. 15,16 From the results of this research, molecular arrangement in the two-dimensional films is formed by competition of van der Waals interaction between alkyl chains and π-π interaction between metal(dmit) 2 units. 16 Further, it is found that increase of stacking areas between metal(dmit) 2 groups enhance conductive properties.…”
