A double-helical S,C-bridged tetraphenyl-para-phenylenediamine and its persistent radical cation?
Chemical Communications Pub Date: 2022-12-31 DOI: 10.1039/D2CC06144A
Abstract
A structurally constrained, double-helical S,C-bridged tetraphenyl-para-phenylenediamine (TPPD) has been synthesized. The stable radical cation of the S,C-bridged TPPD was generated by chemical oxidation, and the electron spin was found to be delocalized over the entire π-conjugated framework. The excellent conformational stability of the neutral molecule facilitated the separation of its enantiomers.
