分子自旋电子学这一新颖而令人兴奋的领域最近引起了人们的极大兴趣，并且已经报道了有希望的结果。利用有机自由基，可以有利于自旋极化和运输过程中的保护提供了新的可能性，但是，首先这些材料，特别是那些沉积在表面上的基本调查，是必需的。在这里，我们强调我们最近的结果，关于表面的功能化与多氯三苯基甲基（PTM）自由基以下五种不同的策略，其中涉及不同性质的相互作用（即货车范德华力，静电，配位键和共价键）。在所有情况下，都证明了分子的磁性特征在表面上持续存在。
The novel and exciting field of molecular spintronics has recently attracted a great deal of interest and promising results have already been reported. The utilisation of organic radicals that could favour spin polarisation and conservation during transport offers new possibilities; however, first a fundamental investigation of these materials, especially those deposited on surfaces, is required. Here we highlight our recent results regarding the functionalisation of surfaces with polychlorotriphenylmethyl (PTM) radicals following five different strategies in which interactions of different nature are involved (i.e. van der Waals, electrostatic, coordination bond and covalent bond). In all cases, it was proved that the magnetic character of the molecule persists on the surface.
