A functioning nanomachine in the form of a supramolecular nanovalve that opens and
closes the orifices to molecular-sized pores and releases a small number of molecules on …

The self-assembly of a series of hexadehydrotribenzo [12] annulene (DBA) derivatives has
been scrutinized by scanning tunneling microscopy (STM) at the liquid− solid interface. First …

Room temperature negative differential resistance (NDR) has been measured through
individual organic molecules on degenerately doped Si (100) surfaces using ultrahigh …

Conductance switching in metal/molecule/metal structures has attracted tremendous and
broad interest. Understanding the switching mechanism, which remained controversial to …

Two switchable neutral bistable [2] rotaxanes have been synthesized, and their chemically
induced mechanical switching has been studied in solution by 1H NMR spectroscopy. One …

Bistable [2] rotaxanes display controllable switching properties in solution, on surfaces, and
in devices. These phenomena are based on the electrochemically and electrically driven …

Self-assembled monolayers (SAMs) of the nitro-substituted oligo (phenylene-
ethynylene)(OPE) 4, 4 '-(diethynylphenyl)-2 '-nitro-1-benzenethiolate on Au {111} were …

A triphenylamine-containing donor− acceptor molecule was designed and synthesized. Its
thin film showed excellent bistable electronic switching behavior with a high ON/OFF current …

Decreasing the size of electronic devices introduces complexities arising from quantum
tunneling effects and the localization of charge in discrete electronic orbitals. Single …

We used electrochemical scanning tunneling microscopy (STM) and spectroscopy (STS) to
elucidate the mechanism of electron transport through individual pyridyl-based Os …
