Description

cis-1,2-Dicyano-1,2-Bis(2,4,5-Trimethyl-3-Thienyl)Ethene CAS NO 112440-46-7 is a specialized organic compound featuring a unique ethene core symmetrically substituted with cyano groups and bulky, electron-rich trimethylthienyl moieties. This molecular architecture makes it a valuable advanced intermediate or functional material in cutting-edge chemical synthesis and materials science. It is primarily sought by R&D chemists and material scientists in the fields of organic electronics, non-linear optics, and as a precursor for complex ligand systems.

Application

• Organic Semiconductor Precursor: Serves as a key building block for the synthesis of π-conjugated molecules and polymers used in organic field-effect transistors (OFETs) and photovoltaic cells.
• Non-Linear Optical (NLO) Materials: Used in research for developing new chromophores with high hyperpolarizability for applications in optical limiting and frequency conversion.
• Coordination Chemistry & Ligand Synthesis: Acts as a precursor for creating sophisticated polydentate ligands for catalysis or metal-organic frameworks (MOFs).
• Chemical Research Intermediate: Employed in academic and industrial R&D for constructing complex, multi-functional organic molecules due to its reactive dicyanoethene group.
• Specialty Dyes and Pigments: Potential use in the development of high-performance dyes with specific light-absorption or emission properties.
