Abstract A strong modification of the electronic properties solution‐processable conjugated polythiophenes by self‐assembled silane molecules is reported. Upon bulk doping with hydrolized fluoroalkyl trichlorosilane, electrical conductivity ultrathin polythiophene films increases up to six orders magnitude, reaching record values for polythiophenes: (1.1 ± 0.1) × 10 3 S cm −1 poly(2,5‐bis(3‐tetradecylthiophen ‐2‐yl)thieno[3,2‐ b ]thiophene) (PBTTT) and 50 20 poly(3‐hexyl)thiophene (P3HT)....

Kelvin probe force microscopy measurements on rubrene single crystals partially coated with fluorinated and non-fluorinated SAM derivatives are employed to determine the SAM-induced surface potentials caused by an interfacial charge-transfer doping process resulting in interface dipole. The potential topographic information turn allow calculation of effective intramolecular electric fields carrier densities due SAM-modified crystals.

Commonly observed variations in photoluminescence (PL) spectra of crystalline organic semiconductors, including the appearance or enhancement certain PL bands, are shown to originate from a small amount structural disorder (e.g., amorphous inclusions embedded crystal), rather than be necessarily related chemical impurities material oxidation. For instance, rubrene, minute such can lead dominant band at 650 nm as result triplet excitons captured and fused these sites, with subsequent emission phase.

Recently, a variety of businesses have appeared not only in the drone's military market but also consumer and service market. The reason for rapid growth is that it possible to produce cheap drones using open source. Although there are lots system controlling drones, people still experience accidents due inexperienced user who purchased drones. These occur from difference between viewpoint Therefore, this paper, we propose User Centric Drone Controller (UCDC) reduce caused by clumsy manipulation.
