Thiophene and its sulfur inhibit indenoindenodibenzothiophene diradicals from low-energy lying thermal triplets
Many qualitative structure–property correlations between diradical character and emerging molecular properties are known. For example, the increase of diradical character further decreases the singlet–triplet ...

Diindeno-fusion of an anthracene as a design strategy for stable organic biradicals
The consequence of unpaired electrons in organic molecules has fascinated and confounded chemists for over a century. The study of open-shell molecules has been rekindled in recent years as new synthetic metho...

Diradical character dependence of third-harmonic generation spectra in open-shell singlet systems
Using a two-site valence configuration interaction model, we reveal the diradical character (y) dependences of the third-harmonic generation (THG) spectra of singlet diradicaloids, which are described by the phot...

(Hyper)polarizability density analysis for open-shell molecular systems based on natural orbitals and occupation numbers
We have developed a method for analyzing the (hyper)polarizabilities of open-shell molecular systems. This method employs the (hyper)polarizability densities based on the natural orbitals and occupation number...

Theoretical Study on Open-Shell Nonlinear Optical Systems
The static second hyperpolarizabilities (γ) of open-shell organic nonlinear optical (NLO) systems composed of singlet diradical molecules are investigated using ab initio molecular orbital (MO) and density fun...
