  Accelerated Luminophore Discovery through Combinatorial Synthesis

  摘要：

  A method for accelerating the discovery of ionic luminophores using combinatorial techniques is reported. The photophysical properties of the resulting transition-metal-based chromophores were compared against a series of analogous, traditionally prepared species. The strong overlap between these two sets confirms the identity of the parallel synthesis products and supports the truthfulness of the combinatorial results. Further support for the combinatorial method comes from the adherence of these complexes to the energy gap law. The relationship between the structure of a complex and its photophysical properties was also considered, and static DFT calculations were used to assess whether it is feasible to predict the luminescent behavior of novel materials.

  into the excited state properties and allowed the prediction of structure/luminescence relationships in this class of commonly used photocatalysts. Models with high prediction accuracy (R2 = 0.89) for emission color were developed on the basis of experimental data. Furthermore, different degrees of nuclear reorganization in the excited state were shown to significantly impact emission energy and excited

  对通过组合平行合成制备的 1440 种不同的杂配 [Ir(C^N)2(N^N)]+ 配合物测量了稳态发射光谱和激发态寿命；发现 72% 的复合物是发光的，并且库的发射最大值跨越了可见光谱 (652-459 nm)。光谱分布范围从宽的无结构带到表现出振动子结构的窄发射。测量的激发态寿命范围在 ~0.1-14 μs 之间。具有连续高斯函数的自动发射光谱拟合揭示了四种不同的激发态测量类别；除了众所周知的金属配体到配体电荷转移 (3MLLCT) 和配体中心 (3LC) 激发态之外，我们的分类还确定了较少探索的混合 3MLLCT/3LC 态的光物理特性。从对这些 Ir(III) 发色团的大部分子集进行 DFT 计算获得的电子结构特征提供了对激发态特性的清晰洞察，并允许预测此类常用光催化剂的结构/发光关系。在实验数据的基础上开发了具有高预测精度 (R2 = 0.89) 的发光颜色模型。此外，激发态中不
