Structure-Property Correlation of Electron Transport Materials in Organic Devices
… deals with organic semiconductors as electron acceptor (n-type) materials in bulk heterojunction (BHJ) solar cells. Important features of an electron acceptor are strong visible light absorption, sufficient high electron mobility and appropriate energy levels with respect to the donor. …

Novel dopants for n-type doping of electron transport materials: cationic dyes and their bases
… by doping, the breakthrough of classical microelectronics became possible. Unlike inorganic semiconductors, organic dyes are up to now usually prepared in a nominally undoped form. However, controlled and stable doping is desirable in many organic-based devices as well. If we succeed in …

Liquid crystalline semiconductors for organic electronics
… and evaluation of novel liquid crystalline materials with light-emitting and or charge-transporting properties. Some of the liquid crystals (LCs) synthesised incorporate photopolymerisable diene or methacrylate end groups, situated at the peripheries of the molecular core. These …

Design and synthesis of nanocrystal heterostructures for optoelectronic applications
… nanocrystals can be used for a variety of optoelectronic applications including light emitting devices (LEDs) and photovoltaics. Their narrow emission spectra make them excellent fluorophors for use in red, green and blue emitting organic LEDs and have been shown to achieve external quantum …

N-type doping of organic thin films using a novel class of dopants
… is carried out. It proves the increase of the electron density with the doping concentration. Conductivities up to 1.9*10^-4 S/cm are obtained for doped NTCDA, which is two orders of magnitude higher than the conductivity of NTCDA doped with (bis(ethylenedithio)-tetrathiafulvalene (BEDT- TTF) …

Synthesis of side-chain polystyrenes for all organic solution processed OLEDs
… solution process techniques. Manufacture of optoelectronic devices by solution process techniques is meant to decrease significantly fabrication cost and allow large scale production of such devices. This dissertation focusses in three series, enveloped in two material classes. The two classes …

Design and synthesis of organic chromophores for imaging, lithography and organic electronics
… lithography and as active components in organic electronic devices. In Chapter 1, a fluorogenic chemosensor to detect saturated nitramine and nitrate ester explosives was devised based on a photochemical reduction reaction. 10-Methyl-9,10- dihydroacridine (AcrH2) was found to transfer a hydride …
