π-Extended Dihydrophenazines with Three-State NIR Electrochromism Involving Large Conformational Changes

π-Extended Dihydrophenazines with Three-State NIR Electrochromism Involving Large Conformational Changes
Hiroshi Shinokubo, Satoru Hiroto, Juri Nagasaki
Getting a piece of the pie: A synthesis of π-extended dihydrophenazines based on anthracenes has been developed. Their charge-transfer characteristic and roof-type structures were determined. They exhibited dynamic motion, like butterfly flapping its wings, by chemical oxidation. Upon oxidation, the absorption was changed in three stages, resulting in intense bands in the near IR region, owing to reversal of a charge-transfer process. Similar phenomena were also observed by electrochemical stimuli. More information can be found in the Full Paper by Juri Nagasaki, Satoru Hiroto and Hiroshi Shinokubo (DOI: 10.1002/asia.201700840).
