Thienyl-linked pyrenes: new green-emitting triads†
Abstract
Novel bis-pyrenyl systems connected through oligothienyl groups have been synthesized, characterized and their optical and electrochemical properties have been studied. By increasing the conjugation length of the spacers, the emission from these systems can be tuned to longer wavelengths. Apart from this, the synthesized molecules have interesting photophysical properties owing to the possible intramolecular charge transfer.
