Dear Colleagues,
this is invitation to joint study of long range forces in low filling factor 3D ordered nano-gels and nano-composites of conjugated polymers and carbon nanotubes. I am a material scientist working in physics and chemistry of highly ordered polymeric and carbon materials. Fifteen years ago we synthesized a 3D ordered polymeric composite material, which consists of nanoparticles of polyacetylene in matrix of poly (vinyl butyral). It was referred to as nanopolyacetylene. It exhibits an array of highly unusual optical properties, such as abnormally high intensity of Raman scattering and stability under laser irradiation. It was shown that most of unusual properties of nanopolyacetylene are linked to vibrational coherence between macromolecules
Then, inter-molecular vibrational coherence was shown for nanogels and nanocomposites of several other conjugated molecules and carbon nanotubes.

It was demonstrated that low filling fuctor 3D ordered nano-composites formed by large conjugated molecules are characterized by:

1. Macroscopic inter-molecular p-electron delocalization;
2. Macroscopic migration of electronic and vibrational excitations without energy losses;
3. Abnormally high cross section of Raman scattering;
4. Absence of frequency dependence of Reyleigh scattering;
5. Abnormally high cross section of X-ray scattering.

We hypothesized that 3D ordered nano-composites with low volume fraction of nanoparticles can form thermodynamic state, which characterized by long range orientational order and phase transition to macroscopic coherent state. It was shown that there are two important pre-conditions for phase transition of large conjugated molecules to macroscopic coherent state: the absence of chemical, conformational and supra-molecular defects in molecular structure, and high translational and rotational mobility of molecules at phase transition temperature.

We suggest that macroscopic coherent state is a ground-state of 3D ordered nanogels and nanocomposites formed by big conjugated molecules.

Large conjugated molecules in gel are positioned at significant distance from each other. Thus, the phase transition is apparently brought about by long-range forces acting between them. We suppose that these forces are a result of coherent interactions of zero-point vibrations and could be referred to as coherent dispersion forces (CDF).
For solid samples of nanopolyacetylene and carbon nanotubes the phase transition to macro-coherent state takes place above liquid nitrogen temperature.

Based on given in assumptions the temperature of phase transition to macro-quantum state should depend on the distance between interacting nanoparticles (macromolecules) and their polarizability.

The macro-quantum phenomena normalized to the same concentration of interacting particles could by classified as follow:

1. Bose condensate of very cold atoms (bosons) in gas phase is "atomic" BEC (1) with very week inter-molecular interactions.
2. Bose condensate of very cold atoms (fermions) in gas phase is "atomic" BEC (2) with strong (super-strong) inter-molecular interactions.
3. The super-fluidity of He4 in liquid phase is "atomic" BEC (3) with medium inter-molecular interactions.
4. Super-conductivity of cold metals in solid phase is "electronic" BEC (4) with strong inter-molecular interactions.
5. High temperature superconductivity in solid phase is "electronic" BEC (5) with very strong inter-molecular interaction.
6. The macro-quantum state formed by big conjugated molecules is a "molecular" BEC (6) with super-strong inter-molecular interaction.
7. The macro-quantum state formed by conjugated radicals is a "molecular" BEC (7) with super-strong inter-molecular interaction.

Thus conjugated macromolecules and conjugated radicals are best objects for creation of solid materials in high-temperature macroscopic quantum state.

I am interested in joint study of long range forces between conjugated molecules (radicals) with any governmental, private or public institutions.
