A Series of 2,5-Bis(5-aryl-2-thienyl)pyrazines with a Linear-Shaped (D-π)2-A System: Synthesis and Study of the Optical Properties Including Fluorosolvatochromism and Proton-Base-Sensing

A series of 2,5-bis(5-aryl-2-thienyl)pyrazines with distinct optical properties tuned by the intramolecular charge transfer (ICT) degree based on the donor strength of the aryl groups have been syn...
