Photovoltaics Based on Thiophene Polymers: A Short Overview

Novel Intramolecular Photocyclization of α-Arylthiophene Derivatives

“…Considerable attention has been paid to the photochemical behavior of thiophene derivatives in a wide range of scientific fields, for example, light emitting materials, photochromic compounds, organic photovoltaic devices, and physical organic chemistry . However, synthetic use of the photoreaction of thiophenes is quite limited, and has mostly consisted of the simple rearrangement between regioisomers, electrocyclization, and [2 + 2] addition. − In addition, a few examples of [4 + 2] addition have also been reported .…”
