Heterocyclic compounds can be divided into two categories: alicyclic heterocycles and aromatic heterocycles. Compounds whose heterocycles in the molecular skeleton cannot reflect aromaticity are called alicyclic heterocyclic compounds. Compound: 4360-63-8, is researched, Molecular C4H7BrO2, about Synthesis, structure, linear and nonlinear properties of tricyanofuran-terminated merocyanine dyes, the main research direction is structure linear nonlinear optical tricyanofuran terminated merocyanine dye.Application of 4360-63-8.
Structural and spectroscopic characteristics of merocyanine dyes are important because of their potential applications in optoelectronics and sensors. Herein we report synthesis, X-ray diffraction characterization of crystal structure, spectroscopic and NMR studies of four merocyanine dyes which, according to their strong donor-acceptor structure, exhibit a second order polarizability (β). Crystallog. studies demonstrated an almost planar structure of all mols. and indicated the occurrence of conformational changes in π-conjugated bridge between donor and acceptor. For three homologues similar packing modes, defined mostly by week C-H···N interactions, were found in crystals. Bond length alternation (BLA) values have been evaluated using crystallog. and NMR data and have shown a correlation to their nonlinear optical activity. Second order polarizabilities for all compounds were measured using hyper Rayleigh scattering (HRS) in solution It was found that the merocyanines studied exhibit very large second order polarizabilities (up to 4.1 10-27 esu), making them potentially useful for materials for second harmonic generation (SHG). Unfortunately, they do not demonstrate acentric packing of chromophores, which is required for SHG in the crystalline state, but may show promise for other applications such as poled polymer blends or for SHG sensing in biol. environments.
