论文摘要
具有量身定制特性的分子和材料的设计是具有挑战性的,因为候选分子必须满足通常难以测量或计算的多个竞争要求。尽管通过生成深度学习产生的分子结构将满足这些模式,但它们通常仅偶然地具有特定的目标特性,而不是通过设计具有特定的目标特性,这使得通过此途径效率低下的分子发现。在这项工作中,我们通过结合一种生成深度学习模型来预测(帕累托)最佳特性的分子,该模型可以预测分子的三维构象与有监督的深度学习模型,该模型将这些模型视为输入并预测其电子结构。通过筛选新生成的分子以获得所需的电子特性,并重复使用HIT分子以偏见来重新训练生成模型,从而实现了(多个)分子特性的优化。该方法被证明是为了找到有机电子应用的最佳分子。我们的方法通常适用,并消除了预测过程中对量子化学计算的需求,使其适合于材料和催化剂设计中的高通量筛选。
The design of molecules and materials with tailored properties is challenging, as candidate molecules must satisfy multiple competing requirements that are often difficult to measure or compute. While molecular structures, produced through generative deep learning, will satisfy those patterns, they often only possess specific target properties by chance and not by design, which makes molecular discovery via this route inefficient. In this work, we predict molecules with (pareto)-optimal properties by combining a generative deep learning model that predicts three dimensional conformations of molecules with a supervised deep learning model that takes these as inputs and predicts their electronic structure. Optimization of (multiple) molecular properties is achieved by screening newly generated molecules for desirable electronic properties and reusing hit molecules to retrain the generative model with a bias. The approach is demonstrated to find optimal molecules for organic electronics applications. Our method is generally applicable and eliminates the need for quantum chemical calculations during predictions, making it suitable for high-throughput screening in materials and catalyst design.
