摘要

合成了连接在邻菲罗啉2,9位的扭曲氨基甲酸D-A-D体系，显示出热激活的延迟蓝色荧光。综合计算和光谱研究揭示了一种混合的局部和电荷转移（HLCT）特征，使系统间的反向交叉，导致延迟荧光。

Thermally Activated Delayed Fluorescence in Aminoacene-linked Phenanthroline

Twisted aminoacene D-A-D systems connected at the 2,9-position of phenanthroline were synthesized, showing thermally activated delayed blue fluorescence. Comprehensive computational and spectroscopic studies revealed a hybrid localized and charge transfer (HLCT) character, enabling reverse intersystem crossing, leading to delayed fluorescence.

期刊介绍： Physical Chemistry Chemical Physics (PCCP) is an international journal co-owned by 19 physical chemistry and physics societies from around the world. This journal publishes original, cutting-edge research in physical chemistry, chemical physics and biophysical chemistry. To be suitable for publication in PCCP, articles must include significant innovation and/or insight into physical chemistry; this is the most important criterion that reviewers and Editors will judge against when evaluating submissions. The journal has a broad scope and welcomes contributions spanning experiment, theory, computation and data science. Topical coverage includes spectroscopy, dynamics, kinetics, statistical mechanics, thermodynamics, electrochemistry, catalysis, surface science, quantum mechanics, quantum computing and machine learning. Interdisciplinary research areas such as polymers and soft matter, materials, nanoscience, energy, surfaces/interfaces, and biophysical chemistry are welcomed if they demonstrate significant innovation and/or insight into physical chemistry. Joined experimental/theoretical studies are particularly appreciated when complementary and based on up-to-date approaches.
