The continuous pursuit of higher power conversion efficiencies (PCEs) in organic photovoltaics (OPVs) has led to the development of sophisticated non-fullerene acceptors (NFAs). Among these, the ITIC (3,9-bis(2-methylene-((3-(1,1-dicyanomethylene)-5,5,11,11-tetrakis(4-hexylphenyl)-dithieno[2,3-d:2’,3’-d’]-s-indaceno[1,2-b:5,6-b’]dithiophene)) derivative family has emerged as a cornerstone. A key member of this family is ITIC-4Cl, distinguished by its chlorination and playing a vital role in advancing OPV technology.

From the perspective of a manufacturer and supplier like us, understanding the nuances of chemical modifications, such as the introduction of chlorine atoms, is essential to producing high-quality materials for our clients. ITIC-4Cl, with its CAS No. 2253663-81-7, benefits significantly from chlorination. This modification influences the molecular packing and electronic energy levels, particularly the HOMO and LUMO, thereby enhancing intermolecular interactions and charge transfer dynamics within the OPV active layer.

Research and our own observations as a supplier indicate that the presence of chlorine atoms in ITIC-4Cl leads to a greater dipole moment compared to its non-chlorinated counterparts. This can contribute to more favorable morphology in the bulk heterojunction and can help in achieving lower energy losses during the charge separation process. For the end-user looking to buy optimized materials, this translates directly to higher PCEs and potentially improved device stability. The dark blue powder form of ITIC-4Cl, with its high purity (>97%), is formulated to harness these benefits effectively.

The synthesis and purification of chlorinated ITIC derivatives require specialized expertise. As a dedicated manufacturer in China, we have invested in advanced production techniques to ensure that our ITIC-4Cl meets the highest standards.
