| 摘 要： | 本文合成了两个二茂铁基查耳酮系化合物3b-3eC5H5FeC5H4CO(CH=CH)nC6H5(n=1,2,3,4)和6a-6cC5H5FeC5H4(CH=CH)nCOC6H5(n=0,1,2)。为了研究这类三岔共轭体系的结构效应,我们用Mossbauer效应为探针, 研究了二茂铁基Fe核周围的电子云分布情况。并用同系因子(1/a)^1^/^N考查了Mossbauer谱参数QS和IS的同系递变规律。结果表明3系中的茂铁基只起代基作用; 6系中的茂铁基则为端基。3系中共轭链的增长引起QS值的减小, 可能是诱导效应所致, 并讨论了取代基的吸电子效应和茂环与铁核间距离对IS和QS值减小的影响。

| Abstract: | The ferrocenyl chalcone compounds C5H5FeC5H4CO (CH = CH)nC6H3 (n = 1, 2, 3, 4) and C5H5FeC5H4 (CH = CH)nCOC6H5 (n = 0, 1, 2) were synthesized to study the forked conjugate systems; one branch acts as the substituent while the other as the terminal group. The Moessbauer effect was used to probe changes in the electronic environment at the iron nucleus. The homologous factor (1/a)2N is used to demonstrate that the quadrupole splitting and isomer shift well conform to the rule of homologous linearity. |
