bis[4,4′-dimethoxy-alpha,alpha’-stilbenedithiolato(2-)]nickel

bis[4,4′-dimethoxy-α,α’-stilbenedithiolato(2-)]nickel (CAS: 38951-97-2) is an organonickel complex consisting of a substituted α,α’-stilbene dithiol ligand chelated with a nickel ion. Its main applications in research and materials science include:

1. Nonlinear Optical (NLO) Materials Research

• Due to its conjugated π-system and metal–sulfur coordination structure, it exhibits strong electron delocalization and excellent nonlinear optical responses (such as second harmonic generation and third-order nonlinear effects).

• Commonly used in the study of optical limiters, all-optical switches, and other optoelectronic devices.

2. Organic Conductive and Optoelectronic Functional Materials

• These nickel dithiolene complexes feature tunable band gaps and relatively high charge mobility, making them useful in organic semiconductors and photoelectric conversion materials.

• Applied in the development of photovoltaic devices, organic field-effect transistors (OFETs), and electrochromic materials.

3. Coordination Chemistry and Materials Chemistry Studies

• Used as a model compound to investigate the electronic structure, spectroscopic properties, and reactivity of metal–sulfur coordination systems.

• Incorporated into polymers or molecular crystals to modulate their electrical, magnetic, and optical properties.

4. Fundamental Research

• Utilized as a research reagent in physical chemistry, spectroscopy, and quantum chemical studies.

• Serves as a reference molecule for exploring band structures and charge transfer mechanisms in organometallic compounds.

⚠ Note

• This compound is mainly used in laboratory research and has not yet seen large-scale industrial applications.

• It is toxic and should be stored under an inert atmosphere (such as argon) in low-humidity conditions, away from light and oxidative environments.
