We constructed monolayer Langmuir–Blodgett (LB) films using a novel molecule C37H40N4O4 synthesized by us. This molecule is a long-chain alkyl derivative with a dinitrobenzene moiety (acceptor subunit) and a dihydrophenazine moiety (donor subunit) bridged by a methylene group with a constant distance and bond angle between the acceptor and donor groups. It behaves as a unimolecular device with control of the potential between the donor and acceptor subunits. We transferred the monolayer film onto a Au(111) substrate and measured nanometre-scale electrical characteristics in the dark or in an evanescent field. Rectifying characteristics and increasing photoconductivity were observed.

Physical Chemistry Chemical Physics

Physical Chemistry Chemical Physics (PCCP) is an international journal co-owned by 19 physical chemistry and physics societies from around the world. This journal publishes original, cutting-edge research in physical chemistry, chemical physics and biophysical chemistry. To be suitable for publication in PCCP, articles must include significant innovation and/or insight into physical chemistry; this is the most important criterion that reviewers and Editors will judge against when evaluating submissions. The journal has a broad scope and welcomes contributions spanning experiment, theory, computation and data science. Topical coverage includes spectroscopy, dynamics, kinetics, statistical mechanics, thermodynamics, electrochemistry, catalysis, surface science, quantum mechanics, quantum computing and machine learning. Interdisciplinary research areas such as polymers and soft matter, materials, nanoscience, energy, surfaces/interfaces, and biophysical chemistry are welcomed if they demonstrate significant innovation and/or insight into physical chemistry. Joined experimental/theoretical studies are particularly appreciated when complementary and based on up-to-date approaches.
