Study On Synthesis Of Symmetrical Ferrocenyl Organometallic Color Materials And Third-order Nonliear Optical Properties

Due to their unique electrochemical and optical properties,ferrocenyl organometallic third-order NLO materials have broad prospect of applications in optical information processing,communications,integrated optics and other high-tech fields.Study on symmetrical ferrocenyl organometallic color third-order NLO materials was one of the hot points in the field of third-order NLO materials.Based on the retrieval of bibliography and the prienciples of the third-order NLO materials,the synthesis and relationship between structure and properties of ferrocenyl organometallic color third-order NLO materials and its test methods were comprehensively reviewed.Three series of 24 ferrocenyl organometallic third-order NLO color materials with different bridge and π-conguegated structure were synthesized.The mechanism of reactions and different kind of effections on the yield were studied.The structure of the materials was confirmed by 1H NMR and MS.A series of 6 symmetrical vinylferrocene third-order NLO materials were synthesized via oxidizing,reduction and wittig reaction with yields between 6.3%and 36.5%.The synthetic method of 1,1’-ferrocenedi-carboxaldehyde was designed and optimized and a series of 9 symmetrical ferrocenyl Schiff-Base third-order NLO materials were synthesized via condensation reaction in the yields between 20.5%and 97.3%.A series of 9 symmetrical ferrocenyl formamide third-order NLO materials which centre was ferrocene,π-electron bridge was formamidyl and π-electron donor was benzoic acid including substituents were synthesized via Friedel-Crafts in the yields between 16.7%and 62.2%.Third-order NLO parameters of three series of 21 materials synthesized were detected with Degenarated Four-Wive Mixing(DFWM)geormetry.The relationship between structure and properties of the materials was studied.As the results that absortion electron group and polyheterocycle are good for materials’ Third-order NLO parameters.Ferrocenyl formamide materials have the highest parameters among the three series materials,while vivlyferrocene materials have the lowest ones.
