A new route to the synthesis of near-infrared absorbing pyrazinopyrazine bridged dyes with intramolecular charge transfer character?
Chemical Communications Pub Date: 2014-03-04 DOI: 10.1039/C4CC01084A
Abstract
A simple and versatile procedure was developed for the synthesis of pyrazino[2,3-b]thieno[3,4-e]pyrazine derivatives with intramolecular charge transfer character. The compounds obtained exhibited a narrower band gap compared to those with one pyrazine bridge.
