Influence of protonation on the structural, spectroscopic and electrochemical properties of 1,3-diazaphenalenes.
Azaphenalenyl compounds are nitrogen-substituted analogues of the all-carbon phenalenyl. They are capable of undergoing protonation/deprotonation reactions, which can be reversibly controlled by acid-base equilibria. In this study, we successfully isolated different protonation states of 1,3-diazaphenalene (DAP) and it...
