Synthesis and properties of π conjugated organic molecular one-dimensional nanomaterials

Abstract

Much attention is turning to nanoscale organic materials, due to many unique properties such as flexibility, high photoconductivity, and nonlinear optical effects that may offer novel applications in nano-optoelectronic devices. We have synthesised new π conjugated organic molecular aggregates using various methods, including template, solid phase organic reaction, thermal evaporation method and organic vapour-solid phase reaction. The dimension-dependent emission properties were observed in the nanowires and nanorods. The approaches are expected to form new general routes for the controlled morphosynthesis of organic molecular materials in restricted dimensions, with controlled size and shape, the solid-state physical properties of which are of great interest.
