Thanks for your contribution! |
请起一个合适的标题 @YfB1125 ,并补充一下PR的简单描述 |
commit代码之前请安装pre-commit,并且使用pre-commit格式化代码,否则code-style-check CI无法通过 |
实验结果的图片,以及相关联的论文也可以在文档中写明 |
文档无法加载和打开,辛苦提交最终版本后检查一下文档、代码的训练、推理,数据加载等各步骤是否正确 |

无关的修改需要还原回去,可以通过合并develop分支解决

可以单独建立一个requirements.txt在案例文件夹下,因为rdkit并不是所有案例都需要

请关注这个comment:#974 (comment)
可以在文档里添加上每个模型的训练结果图片。 |
对数据集的格式做一个说明吧 |
提供的评估命令是有问题的,辛苦检查一下 |
TADF材料分子的光电性质预测

Describe
有机发光二极管(OLED)具有高效率、结构灵活和低成本的优势,在先进显示和照明技术中受到广泛关注。在有机发光二极管器件中,电注入载流子以1:3的比例形成单线态和三线态激子。以纯荧光材料为发光材料构建的OLED发光效率IQE理论极限为25%。另一方面,有机金属复合物发光材料通过引入稀有金属(Ir,Pt等)带来强自旋轨道耦合(SOC),可以将单线态激子通过系间窜越过程转化成三线态激子,从而利用三线态激子发出磷光,其IQE可达100%,但是稀有金属价格昂贵,为推广使用带来了阻碍。热活化延迟荧光材料(TADF)为解决这些问题提供了新思路,并引起了广泛关注。在TADF中,三线态通过逆系间窜越过程(RISC)转化成单重态并发出荧光,从而实现100%的IQE,而RISC过程很大程度上取决于最低单线态(S1)和最低三线态(T1) 之间的能隙(ΔEST)。根据量子力学理论,ΔEST相当于HOMO和LUMO之间的交换积分的两倍。因此TADF分子的常见设计策略是将电子供体(D)和电子受体(A)以明显扭曲的二面角结合以实现HOMO和LUMO在空间上明显的分离。然而,与ΔEST相反,振子强度(f)需要较大的HOMO和LUMO之间的重叠积分,这二者之间的矛盾需要进一步平衡。
