Organic fluorescent small molecule optical property prediction method based on deep neural network

Abstract

The invention provides an organic fluorescent small molecule optical property prediction method based on a deep neural network. According to the method, a new organic fluorescent small molecule database is established, molecular descriptors and molecular fingerprints are adopted to extract molecular information, and a multi-layer neural network and a convolutional neural network are input for deep learning training to obtain an organic fluorescent small molecule optical property prediction model; the characteristic information of the to-be-predicted organic fluorescent micromolecules and the experimental solvent thereof are input into the trained organic fluorescent micromolecule optical property prediction model so as to predict the optical property of the to-be-predicted organic fluorescent micromolecule. The method can accurately predict the optical properties (the average relative error is less than 5%) of the organic fluorescent small molecules, so that the development efficiency of the organic fluorescent small molecules is improved.
