Radical anion salts of metal phthalocyanines have been providing a new family of compounds which can potentially possess promising optical, magnetic and conducting properties. Essential progress in this field has been reached only recently when series of salts of phthalocyanines with different metals and axial substituents were obtained. In this work we summarize our recent results about the radical anion salts of titanyl (Ti^IVOPc) and vanadyl (V^IVOPc) phthalocyanines and nine new salts of these phthalocyanines are discussed. Different synthetic approaches for the preparation of these salts are presented, and the effect of the size and shape of counter cations on the crystal structures of the salts and consequently their magnetic and optical properties are considered. The {Ti^IVO(Pc˙³⁻)}˙⁻ radical anions have an S = 1/2 spin on the Pc˙³⁻ macrocycle, whereas the {V^IVO(Pc˙³⁻)}˙⁻ radical anions have two S = 1/2 spins on both the Pc˙³⁻ macrocycle and the central V^IV atom. Therefore, it is possible to compare the magnetic properties of isostructural compounds with different magnetic states of metal phthalocyanines. We also discuss the effect of reduction on the molecular structure and the optical and magnetic properties of negatively charged titanyl and vanadyl phthalocyanines.

与钛氧基和钒基酞菁自由基阴离子形成的盐。阳离子的分子设计和对结构，磁和光学性质的影响†

金属酞菁的自由基阴离子盐已提供了一种新的化合物家族，这些化合物可能具有广阔的光学，磁性和导电性能。仅在最近获得具有不同金属和轴向取代基的酞菁盐系列时，才在该领域取得实质性进展。在这项工作中，我们总结了有关钛氧基（Ti ^IV OPc）和钒基（V ^IV OPc）酞菁自由基阴离子盐的最新结果，并讨论了这些酞菁的9种新盐。提出了制备这些盐的不同合成方法，并考虑了抗衡阳离子的大小和形状对盐的晶体结构的影响，并因此考虑了它们的磁性和光学性质。{Ti^IV O（PC ^3- ）}˙ ^-自由基阴离子具有小号在PC = 1/2旋^3-大环化合物，而{V ^IV O（PC ^3- ）}˙ ^-自由基阴离子有两个小号= 1/2在Pc ^3-大环和中心V ^IV原子上自旋。因此，可以比较金属酞菁具有不同磁态的同构化合物的磁性。我们还讨论了还原对带负电的钛氧基和钒基酞菁的分子结构以及光学和磁性的影响。
