MULTIDIMENSIONAL ORGANIC CONJUGATED SYSTEMS: SYNTHESES, CONFORMATION AND PROPERTY INVESTIGATIONS

Abstract

Organic conjugated materials are important for developing new functional devices owing to its structural versatility. The principal aim of this work is to study the effects of chemical structures, conformations and dimensionality on the properties of π-conjugated systems. It has been well established that the physical, thermal, optical, electrochemical, and electronic properties of the π-conjugated systems are highly dependent on their conformations. Moreover, the understanding of the conformation-property relationships will lead to better designs of π-conjugated systems for targeted applications such as organic electronics, optoelectronics, sensors, and optical switch. In this work, the designs, syntheses, and purification of multi-dimensional conjugated architectures (one-, two-, and high-dimensional conformations) are studied in effort to establish a valid structure-property relationships. The potential uses of synthesized π-conjugated systems for sensors are studied and explored.
