Curved π-conjugated molecules and open-shell structures have attracted much attention from the perspective of fundamental chemistry, as well materials science. In this study, chemistry 1,3-diradicals (DRs) embedded in curved cycloparaphenylene (CPPs) structures, DR-(n+3)CPPs (n = 0–5), was investigated to understand effects curvature system size on spin–spin interactions singlet versus triplet ...

This work demonstrates the unique approach of introducing divacancy imperfections in topological Stone-Wales type defected graphene quantum dots for harvesting both singlet and triplet excitons, essential fabricating fluorescent organic light-emitting diodes. Here, we first reveal that structural relaxation these systems establishes high-spin state as stable ground at room temperature, thereby ...

the subject of the present article is the problem concerning the unity of attributes and its relation to the unity of referent and multiplicity of concepts. in this problem, the theory of non-revealingness (‘adam-i kāshifiyat) of the multiplicity of concepts from multiplicity of referent is proved; and the rival theory, i.e., the revealingness of the multiplicity of concept from the multiplicit...

The calculation of spectra of two coupled spin systems within the stochastic Liouville equation formalism is systematized by the use of the coupled muitipob-operator representation. The Liouville superoperator of the system is easily calculated in this representation in a unified way for all interactions by using a generalized Wigner-E&art theorem in operator space. The spectrum is defined as t...

Tailoring of spin state energetics transition metal complexes and even the correct prediction resulting is still a challenging task, both for experimentalist theoretician. Apart from complexity in solid imposed by packing effects, molecular factors ordering are required to be identified quantified on equal rights. In this work we experimentally record states SCO energies within an eight-member ...
