我们证明了在受控环境中蒸发布拉特基衍生物的可能性，得到了保留（多）基磁性的薄膜。然而，它们的热蒸发是具有挑战性的。我们用热力学概念分析了蒸发过程和薄膜的形成，并用第一性原理计算描述了材料的性质。多个自由基位点的存在使自由基更具活性，缩小了蒸发的窗口，因此，有利于分子的组装和岛屿的形成，而不是二维生长。
We demonstrate the possibility to evaporate Blatter radical derivatives in a controlled environment obtaining thin films that preserve the (poly)radical magnetic character. However, their thermal evaporation is challenging. We analyse the evaporation process and the thin film formation using thermodynamic concepts and describe the material properties also using first principles calculations. The presence of more than one radical site makes the radical more reactive, narrowing the windows left for evaporation, thus, favouring the assembly of molecules and island formation rather than two-dimensional growth.
