Abstract

TCNQ (TCNQ= tetracyanoquinodimethane) salts have good conductivity. The magnetic properties of substituted benzylpridiniums, such as ferromagnetism, antiferromagnetism and spin Peierls transition, have widely been investigated. In order to obtain some new materials with both conductivity and magnetism, two new organic salts, [NO2BzPy]Cl (1) and [NO2 BzPyNH2]Cl (2), were synthesized and characterized. Further more, two new charge transfer salts, [NO2BzPy] [TCNQ]2 (3) and [NO2BzPyNH2] [TCNQ]2 (4) were synthesized and characterized. The tested results of elementary anAlysis of charge transfer salts (3) and (4) were consistent with theoretical values, and the results of IR indicated that there exist TCNQ and TCNQ anions. One-dimensional molecular column of TCNQ has been formed. Partial charge transfer takes place from [TCNQ]2- to cation.

摘要

四氰基对苯二醌二甲烷（TCNQ）盐具有良好的导电性。人们对取代苄基吡啶鎓的磁性，如铁磁性、反铁磁性和自旋佩尔斯转变，进行了广泛研究。为了获得兼具导电性和磁性的新材料，合成并表征了两种新型有机盐，即[NO2BzPy]Cl（1）和[NO2BzPyNH2]Cl（2）。此外，还合成并表征了两种新型电荷转移盐，即[NO2BzPy][TCNQ]2（3）和[NO2BzPyNH2][TCNQ]2（4）。电荷转移盐（3）和（4）的元素分析测试结果与理论值一致，红外光谱结果表明存在TCNQ和TCNQ阴离子。已形成TCNQ的一维分子柱。部分电荷从[TCNQ]2-转移到阳离子上。
