Self-assembled monolayers (SAMs) of push–pull chromophores are important for surface functionalization and have various applications in optoelectronics, sensors, and other fields. These chromophores consist of an electron-donating unit (push) and an electron-withdrawing unit (pull) connected by a conjugated bridge. Their unique electronic and optical properties make them useful for improving the performance of devices such as dye-sensitized solar cells (DSSCs) and perovskite solar cells. In DSSCs, push–pull chromophores can enhance charge transfer and improve the efficiency of the cells. In perovskite solar cells, they can help in passivating defects and improving stability. Additionally, push–pull chromophores can be used as dielectric materials in organic field-effect transistors (OFETs) due to their ability to create dipole moments that influence the dielectric properties of the layers. The organization of these chromophores on surfaces is crucial for achieving the desired functional properties. Research has shown that the use of push–pull chromophores in SAMs can lead to improved performance in various electronic and optoelectronic devices. The study highlights the importance of controlling the molecular structure and the self-assembly process to optimize the properties of these materials for specific applications.Self-assembled monolayers (SAMs) of push–pull chromophores are important for surface functionalization and have various applications in optoelectronics, sensors, and other fields.
