我们能根据分子特性预测界面偶极子吗?

Can we predict interface dipoles based on molecular properties?

Johannes J. Cartus, Andreas Jeindl, Oliver T. Hofmann

摘要:

我们应用高通量DFT计算和符号回归混合无机/有机界面的目的是提取物理上有意义的相关性吸附诱导的功函数的修改和属性的成分。我们分别调查两种情况:假设,独立的自组装单分子膜与一个大的固有偶极矩,和金属有机界面与一个大的电荷转移诱导偶极子。对于前者,我们发现-没有显着的事先假设-Topping模型,从文献中预期。对于后者,发现了高度精确的相关性,然而,这显然是非物理的。

英文摘要:

We apply high-throughput DFT calculations and symbolic regression to hybrid inorganic/organic interfaces with the intent to extract physically meaningful correlations between the adsorption-induced work function modifications and the properties of the constituents. We separately investigate two cases: Hypothetical, free standing self-assembled monolayers with a large intrinsic dipole moment, and metal-organic interfaces with a large charge-transfer induced dipole. For the former we find - without notable prior assumptions - the Topping model, as expected from literature. For the latter, highly accurate correlations are found, which are, however, clearly unphysical.
