Organic Charge Transfer Salts. II. Emission Spectrum of an Organic Charge Transfer Salt, 2,4,6-Triphenylthiopyrylium–1,1,3,3-tetracyanopropenide

Mixed valency in organic charge transfer complexes.

Mixed-valence (partial charge transfer state) and segregated stacking are the key factors for constructing organic metals. Here, we discuss the ionicity phase diagrams for a variety of charge transfer systems to provide a strategy for the development of functional organic materials (Mott insulator, semiconductor, superconductor, metal, complex isomer, neutral-ionic system, etc.).

Charge-Transfer Interactions in Organic Functional Materials

Our goal in this review is three-fold. First, we provide an overview of a number of quantum-chemical methods that can abstract charge-transfer (CT) information on the excited-state species of organic conjugated materials, which can then be exploited for the understanding and design of organic photodiodes and solar cells at the molecular level. We stress that the Composite-Molecule (CM) model is...

The ubiquitous 1100 charge ordering in organic charge-transfer solids

Charge and spin-orderings in the 1 4 -filled organic CT solids are of strong interest, especially in view of their possible relations to organic superconductivity. We show that the charge order (CO) in both 1D and 2D CT solids is of the ...1100... type, in contradiction to mean field prediction of ...1010... CO. We present detailed computations for metal-insulator and magnetic insulator-insulat...

Multiferroicity in an organic charge-transfer salt that is suggestive of electric-dipole-driven magnetism.

Multiferroics, showing simultaneous ordering of electrical and magnetic degrees of freedom, are remarkable materials as seen from both the academic and technological points of view. A prominent mechanism of multiferroicity is the spin-driven ferroelectricity, often found in frustrated antiferromagnets with helical spin order. There, as for conventional ferroelectrics, the electrical dipoles ari...
