2-(p-Nitrophenoxycarbonyloxy)ethyl methacrylate [N1293] is a methacrylate monomer that reacts with primary amino groups to introduce functional moieties via a urethane linkage. In addition to application to functional monomer synthesis, it is also possible to introduce functional moieties into (co)polymers and provide an advantageous approach to incorporating functional groups that are not compatible with polymerization conditions.

Graphitic carbon nitride (g-C₃N₄) has received a great deal of attention as a metal-free photocatalyst for applications such as water splitting and organic matter removal. Heptadine chloride [T4145] and melem [M3538] which are partial structures of g-C₃N₄ can be synthesized as high-performance light-emitting materials by introducing appropriate substituents. They are also applied for a monomer unit of MOF and COF.

DMPESI [D6365] can be used for surface treatment of perovskite layers to improve the conversion efficiency and durability of devices. Compared to PEAI, it has stronger bonding ability to perovskite surface. In addition, when used for the surface treatment of FAPbI₃, it suppresses the transition from α layer to δ layer.

The charge transport layer is one of the key elements in perovskite solar cells because it is responsible for the power conversion efficiency of perovskite solar cells, PTAA [P3179] can be used as a hole transport layer in perovskite solar cells, perovskite LEDs, and organic transistors, and suitable for various solution processes.
