3D ordered composites of nanopolyacetylene: Mechanism of self-organization and properties

Abstract

In 1987-89 were synthesized soluble nano-composites of polyacetylene (NPA) with an abnormally high intensity of Raman scattering and high stability under laser radiation. Here we demonstrate that the key pre-condition to the outstanding characteristics of NPA is the vibrational and rotational mobility of nano-particles, provided by plasticized layers of water on their surface. The results afford a connection between optical properties of NPA and the three-dimensional coherent order arising from self-organization of nanoparticles at synthesis and during film formation. The driving force behind self-organization is the abnormal high vibrational hyper-polarizability of macromolecules leading to coherent dispersive interactions. The principles of synthesis employed can further be used to create 3-D coherently ordered photon crystals and meta-materials.
