While 3-(Dicyanomethylidene)indan-1-one (2HIC, CAS 1080-74-6) is widely recognized for its pivotal role in advancing non-fullerene acceptors (NFAs) for organic photovoltaics (OPVs), its utility extends far beyond this primary application. The inherent electronic and structural properties of 2HIC make it a valuable building block for a diverse array of advanced organic electronic and photonic materials. As a dedicated supplier of high-purity chemical intermediates, we are committed to supporting innovation across the entire spectrum of organic electronics research and manufacturing.

The strong electron-withdrawing character of 2HIC is a key feature that enables its application in organic field-effect transistors (OFETs). The development of efficient n-type (electron-transporting) organic semiconductors is a significant challenge in creating complementary circuits. By incorporating 2HIC into molecular designs, researchers can lower the lowest unoccupied molecular orbital (LUMO) energy levels, thereby facilitating electron injection and transport. This property is essential for creating high-mobility n-type materials that can complement p-type semiconductors in various electronic devices, including flexible displays and printed electronics.

Furthermore, the electron-deficient nature of 2HIC positions it as a promising candidate for charge-trapping layers in organic memory devices. In such applications, the ability of a material to effectively capture and retain charge carriers (holes or electrons) is critical for storing information. The strong electron affinity of the 2HIC moiety can be leveraged to create trapping sites for holes. When integrated into a suitable matrix, these units can respond to applied voltages, leading to changes in transistor characteristics that represent stored data bits. This opens avenues for low-cost, flexible memory solutions.

The domain of nonlinear optics (NLO) also benefits significantly from chromophores incorporating 2HIC. Molecules that exhibit large second-order NLO properties are vital for technologies like optical communications, data processing, and frequency conversion. The D-A structure inherent in 2HIC-based chromophores, combined with its strong electron-accepting power, leads to substantial intramolecular charge transfer, which is directly correlated with high NLO response. For example, research on chromophores linking electron-donating groups like tetrathiafulvalene (TTF) to the 2HIC acceptor unit has demonstrated significant NLO activity. This makes 2HIC a crucial intermediate for the synthesis of materials used in next-generation photonic devices.
