5-Bromo-4-((2-ethylhexyl)oxy)-2-thiophenecarboxaldehyde (EHOThCHO-Br) is the building block that is used for the synthesis of ultra-narrow band-gap non-fullerene acceptors (NFAs) such as IEICO, IEICO-4F and IEICO-4Cl.
Absorption of IEICO-4F mainly locates in the deep-red and near infrared region, ranging from ~ 700 nm to ~ 1000 nm.
