eng	Pyridiniumamines with Various Spatial Arrangement	Organic redox-active substances are of great interest, for instance for redox flow batteries (RFB). The RFBs, consisting of a redox-active material dissolved in electrolyte, may store large amount of electricity and feature operationally easy (dis)charging. Hence, they may significantly reduce fluctuating electricity production of renewable resources such as photovoltaics and wind farms. A typical redox flow battery consists of two electrolyte reservoirs, from which these electrolytes are pumped via two porous carbon electrodes. A suitable organic redox material is crucial for RFBs. Reversibility of the given redox process, water-solubility and (electro)chemical stability are basic requirements on organic molecule to be applied in aqueous RFBs. Pyridinium has been utilized in target molecules as well-known redox center, while the central part is made of an amine. Three target molecules based on parent 4-aminopyridine, di(pyridin-4-yl)amine and tri(pyridin-4-yl)amine were designed and prepared. Subsequently, these pyridine derivatives underwent N-quaternization using propane-1,3-sultone. All prepared salts were subjected to primary voltammetric and water-solubility testing. Thus, the synthetic strategy and characterization of target molecules will be discussed in this contribution.	flow batteries; pyridine; pyridinium; quarternization
