Assembly, structure and thermoelectric properties of 1,1′-dialkynylferrocene ‘hinges’

Abstract

Dialkynylferrocenes exhibit attractive electronic and rotational features that make them ideal candidates for use in molecular electronic applications. However previous works have primarily focussed on single-molecule studies, with limited opportunities...

Impact of the terminal end-group on the electrical conductance in alkane linear chains

“…1–8 Moreover, the electrical conductance and Seebeck coefficient of single molecules can be controlled in a deterministic manner by chemically varying their anchor groups to external electrodes and this research focuses on this parameter. 9–16…”

“…[1][2][3][4][5][6][7][8] Moreover, the electrical conductance and Seebeck coefficient of single molecules can be controlled in a deterministic manner by chemically varying their anchor groups to external electrodes and this research focuses on this parameter. [9][10][11][12][13][14][15][16] In this study, we look to demonstrate that the nature or type of anchor groups used to bind molecules to metal electrodes also affects transport through single-molecule junctions. [17][18][19][20] This research describes the effects of anchoring groups on the conductance of single molecules using n-alkane single chains as a model system.…”

20-State Molecular Switch in a Li@C60 Complex

“…This inspiring idea encouraged a significant number of researchers to explore this area of science. Molecular switching is one of the essential search areas as it provides a solution to extremely expand data storage. − The current switching devices employ silicon-based technologies, one disadvantage of which is the massive number of silicon atoms involved to save a single signal (i.e., 0 or 1). In comparison, one single magnetic atom was evidenced to perform as a reliable memory, capable of being switched between two magnetic states …”

Orientation preference control: a novel approach for tailoring molecular electronic functionalities

“…Molecular backbones with asymmetric anchors at both terminals are of great interest due to their unique properties, like rectification and tunable thermoelectric behaviors. 15–21 This is because the presence of an asymmetric anchor/electrode interface not only leads to an asymmetric coupling strength between the molecule and the electrodes, 17,18 but also influences the energy difference between the electrode Fermi level and the frontier molecular orbital. 19–21 The electron transport properties of asymmetrically anchored molecules have been extensively investigated at both single-molecule 17,18,22–24 and self-assembled monolayer (SAM) levels.…”
