Redox properties of Bis-Triarylamines and ligand properties of Thianthrenophane
The one electron oxidation potential of ten TAAs with all permutations of Cl , OMe- and Me-substituents in the three p-positions were determined by CV. The half wave potential of the first oxidation wave correlates linearly with the number of Cl- and OMe-substituents. AM1-CISD derived values of the …

Neutral And Charged Bis(Triarylamines) For Use In Grid Scale Battery Technologies
<p>Energy storage systems allow flexibility in control and maintenance of the electric grid while integrating renewable energy resources to mitigate carbon emissions. Redox flow batteries (RFBs) are stationary energy storage systems that convert chemical energy to electrical energy by …

Photophysics of Biological and Synthetic Multichromophoric Systems : Spectroscopic Investigations of Bacterial Light-Harvesting Complexes and of Carbonyl-Bridged Triarylamine Derivatives
… systems, based on carbonyl-bridged triarylamines (CBTs) Different methods of optical spectroscopy and optical microscopy have been used to investigate these systems. The first part of this work discusses the results of time-resolved optical spectroscopy in a picosecond-range on …

Novel Catholyte and Electrolyte Optimisation for Aqueous Organic Redox Flow Batteries
… first results chapter (Chapter 3), a series of triarylamines was synthesised. Initial electrochemical testing (using cyclic voltammetry) revealed one of these candidates, amino-functionalised 4-amino-trisphenyl amine, proved to be the most promising. However, battery cycling with this as the …

Synthesis, Self-Assembly and Photophysical Properties of Multichromophoric Systems
… versatile functionalization of carbonyl-bridged triarylamines. Both multichromophoric compounds show efficient energy transfer, evidenced by steady-state and time-resolved spectroscopy. The compound bearing naphthalimides in the periphery funnels the energy from the periphery to the …

Synthesis, characterisation and application of low molecular weight and polymeric 1,3-di-2-thienylbenzo[c]thiophenes
… in DTITNPDs. Thus, the combination of DTITN and triarylamines leads to DTITNPD, where the values of both energy levels can be varied. Novel DTITNPDs exhibit smaller band gap compared to DTITNs. The better delocalised HOMO level in the DTITNPDs compared to DTITNs leads to novel hole transport dyes …

Donor-Acceptor Block Copolymers in Organic Electronics - Spectroscopy, Charge Transport, Morphology and Device Application
… to PvTPA, we have characterised further poly(triarylamines) with different electron-rich substituents at the TPA units in OFETs. All these polymers are amorphous side-chain polymers. We found the charge carrier mobility to be independent of the molecular weight, though allowing an adjustment …

Elektronentransferprozesse in gemischtvalenten Systemen, Redoxkaskaden und Polymeren auf Basis von Triarylaminredoxzentren
Im Rahmen dieser Arbeit wurden Elektronentransferprozesse in Systemen, die auf Triphenylaminredoxzentren basieren, mit Hilfe spektroskopischer und elektrochemischer sowie spektroelektrochemischer Methoden studiert. Im ersten Teil der vorliegenden Arbeit wurden Bistriarylaminsysteme analog zu …
