TLDR
In this article, a method to arrange a TTF-TCNQ-based complex by the difference between the electrochemical half-wave potentials of the donor and acceptor molecules is proposed to predict electrical properties of the complex.Abstract:
Current theories on the origin of high electrical conductivity in TCNQ-based materials emphasize the need for incomplete charge transfer as well as segregated stacks of donor and acceptor molecules and uniform spacing within the stacks. The requirements for an “organic metal” are discussed in terms of partial charge transfer. An examination of 61 structurally related TTF–TCNQ, based complexes suggests that the combinations with the redox potential −0.02≤E1(D)−E1(A)≤0.34 V have a high possibility of being “organic metals.” A method to arrange the complex by the difference between the electrochemical half-wave potentials of the donor and the acceptor molecule is proposed to predict electrical properties of the complex.read more

Nature and Origin of Stable Metallic State in Organic Charge-Transfer Complexes of Bis(ethylenedioxy)tetrathiafulvalene
TL;DR: The BEDO-TTF molecule proves to be an excellent source for stable metals irrespective of the structure, shape, size, and electron affinity of counter components as discussed by the authors, and the crystal structure of metallic BEDDO-T TF complexes indicates a strong aggregation of donor molecules into a two-dimensional (2D) layered structure by the aid of both intermolecular CH···O and side-by-side heteroatom contacts.

Possibility of synthesizing an organic superconductor
TL;DR: In this article, London's idea that superconductivity might occur in organic macromolecules is examined in the light of the BCS theory of superconductivities and it is shown that the criterion for the occurrance of such a state can be met in certain organic polymers.

Superconducting fluctuations and the Peierls instability in an organic solid

TL;DR: In this article, the discovery of extraordinary conductivity maxima in a class of organic charge transfer salts is interpreted as resulting from superconducting fluctuations at high temperatures, and a possible mechanism for achieving high temperature superconductivity is suggested based on the electron-phonon interaction, in the strong coupling limit, and the Peierls soft-mode instability in pseudo-one-dimensional systems.
