Chloroboronsubphthalocyanine [B6296] is a 14π-electron system compound with a bowl-shaped, non-planar structure, comprised of a boron atom surrounded by a ligand composed of three isoindoline units. Due to its strong absorption, with a maximum between 560-600 nm, and its red-orange emission, it has been widely investigated as an optical material for applications such as organic photovoltaics (OPVs), organic light-emitting diodes (OLEDs), and photodynamic therapy (PDT).

Methacrylate ester monomer [N1293] having a p-nitrophenyl carbonate moiety that reacts with an amino group. N1293 is applicable to polymer synthesis by controlled radical polymerization, and allows for the introduction of functional moieties into the polymer after polymerization.

2-Phenylethylamine hydroiodide [P2213], 1,2-benzenediethanamine dihydroiodide [B6569] and 1,4-benzenediethanamine dihydroiodide [B6570]  have been reported to improve the stability of solar cell devices when used for the surface treatment of perovskite layer. They can also be available for field effect transistors using Sn-based perovskite.

These electron-accepting building blocks have been used for both p-type and n-type materials in organic photovoltaics as well as hole transport materials in perovskite solar cells. The energy levels of the materials can be adjusted by selecting different building blocks.
