Synthesis, Structure, and Opto-electronic Properties of Regioisomeric Pyrene–Thienoacenes

Three regioisomeric sulfur-bridged pyrene–thienoacenes (PTAs) have been synthesized. The crystal structures and optoelectronic properties of these ring-fused PTAs and their ring-opened precursors have been fully investigated. Among these isomers, the [3,4]-extended compound (4-S-PTA) shows the most...

Description
Summary:Three regioisomeric sulfur-bridged pyrene–thienoacenes (PTAs) have been synthesized. The crystal structures and optoelectronic properties of these ring-fused PTAs and their ring-opened precursors have been fully investigated. Among these isomers, the [3,4]-extended compound (4-S-PTA) shows the most pronounced spectral red-shift and highest quantum yield as well as large transistor mobility.
