Ferrocenylcyanide is a valuable precursor for preparation of nitrogen-containing ferrocenyl ligands. Originally, ferrocenylcyanide was prepared from ferrocenecarboxy- aldehyde by multi-steps transformations, at evaluated temperature. Very recently, a modi… 相似文献

二茂铁具有独特的夹心刚性结构,炔基具有刚性和线性,茂铁基与炔基的结合使得二茂铁炔基具有两者的优点,成为用途广泛的刚性构筑块, 而且茂铁炔基因体系扩展的π-π电子离域产生了分子导线效应。本文介绍了近几年来茂铁炔基在分子导线、分子开关、分子马达、化学传感器、非线性光学材料、催化剂等光电功能材料领域的研究进展。 相似文献

The ruthenium unit was introduced into the redox-active molecular polygon to assembly new Ru-Fc metallocycles (Compound 1), in which the redox active (ferrocene) and fluoresecent (ruthenium) signaling subunits are directly attached by the putative cation-binding sites. The compound 1 displayed high selectivity for Ca^2 by electrochemical tests. The measurements of the fluorescence spectra on titration of 1 with Ca^2 , Li^ , Na^ , K^ , Mg^2 or Ba^2 ion indicate the unique ability of 1 to detect Ca^2 ions selectively. 相似文献
