描述This brief investigates the diradical character, which is one of the ground-state chemical indices for "bond weakness" or "electron correlation" and which allows researchers to explore the origins of the electron-correlation-driven physico-chemical phenomena concerned with electronic, optical and magnetic properties as well as to control them in the broad fields of physics and chemistry. It then provides the theoretical fundamentals of ground and excited electronic structures of symmetric and asymmetric open-shell molecular systems by using model molecular systems. Moreover, it presents the theoretical design guidelines for a new class of open-shell singlet molecular systems for nonlinear optics (NLO) and singlet fission.

Introduction,system. The diradical character, which is one of the quantum-chemically well-defined chemical indices and indicates the singlet open-shell nature, is employed for classification of arbitrary electronic structures into three categories, i.e., weak, intermediate and strong electron correlation regions

Diradical Character View of (Non)Linear Optical Properties,ic diradical models with two electrons in two active orbitals. The analysis results highlight the differences of optical response properties between open-shell and closed-shell molecular systems, and contribute to the construction of novel molecular design guidelines for highly efficient nonlinear optical systems.
