potential contribution in the fields of nanoelectronics and low-dimensional chemistry/physics. Based on molecular charge transfer salts, we demonstrate, for the first time, the rational construction of molecular electron-conducting wires encapsulated in a proton-conducting matrix, which possibly paves the way to ionoelectronics. As expected from the molecular structure of the newly designed complex anion
绝缘分子线因其在纳米电子学和低维化学/物理领域的潜在贡献而受到广泛关注。基于分子电荷转移盐,我们首次证明了封装在质子传导基质中的分子电子导线的合理构造,这可能为离子电子学铺平道路。正如新设计的复合阴离子的分子结构(即在四个边缘具有氢键位点的螺旋桨状结构)所预期的那样,在晶体内部构建了一个三维氢键框架,其中包含一维阵列电子供体四硫富瓦烯 (TTF)。从单晶晶体学和光谱学研究来看,澄清了阴离子的非化学计量去质子化和 TTF 的部分氧化,而阴离子是电子惰性的。通过直流和交流电导率测量证实了电子和质子的中等电导率。此外,磁化率数据证实了 TTF 导线的电子隔离。
