Abstract

The intermolecular electronic coupling (transfer integral) and the intramolecular vibronic coupling (reorganization energy) are key parameters determining the transport properties of organic electronic materials. Using quantum mechanism calculations, we revealed the correlation between the reorganization energies and the partial charge difference values on the conjugated acene backbone, which can be used to evaluate the reorganization energies for acene and acene derivative systems with the same conjugated backbone but different substitutional groups. We used rigorous quantitative functions to investigate the electronic coupling oscillation behavior in slipped-cofacial stacking acene and acene derivative molecules, and revealed characteristic parameters in the electronic coupling oscillation. We suggest using a similar strategy to establish the quantitative structure–activity relationship database for different families of organic semiconducting materials.

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.
