Study the Influence of Quantum Interference on the Electrical Conductance and Thermoelectric Properties of Molecular Junctions : Synthesis and Thermoelectricity
(2021)- Abstract
- This thesis mainly describes our efforts towards the study of the quantum interference of electronic conductance and thermoelectric properties in molecular junctions.
Chapter 1 introduces the concepts of the charge transport in single-molecule junctions, include the electrical conductivity and thermopower which are the main parameters to assess the efficiency of the single-molecule junctions.
Chapter 2 describes the design and synthesis of the molecules used in the single-molecule junctions, and shows our progress how to tune the electron transport by manipulating the structures of molecules in the single-molecule junctions.
Chapter 3 mainly describes the optimization of the Sonogashira coupling and Ti-mediated functional... (More) - This thesis mainly describes our efforts towards the study of the quantum interference of electronic conductance and thermoelectric properties in molecular junctions.
Chapter 1 introduces the concepts of the charge transport in single-molecule junctions, include the electrical conductivity and thermopower which are the main parameters to assess the efficiency of the single-molecule junctions.
Chapter 2 describes the design and synthesis of the molecules used in the single-molecule junctions, and shows our progress how to tune the electron transport by manipulating the structures of molecules in the single-molecule junctions.
Chapter 3 mainly describes the optimization of the Sonogashira coupling and Ti-mediated functional group transformation for the synthesis of meta-OPE3 derivatives. These derivatives offer a chance to systematically study the correlation between the molecular structures and trasport properties in the single-molecule junctions.
Chapter 4 is aiming at providing a possible strategy for synthesis of β-substituted porphyrins using the MacDonald [2+2] approach and [3+1] method. These porphyrins are designed for the use in the single-molecule junctions.
