A novel conjugate of a helical nonapeptide and an oligo(phenyleneethynylene) (OPE) having a nitro group at a molecular terminal was synthesized. Both components have a dipole. The peptide has a disulfide group at the N-terminal for immobilization on gold. In order to investigate the electric field effect of the helical peptide dipole on the OPE and molecular structure by the dipole–dipole interaction between the two components, the electronic structure of the OPE was spectroscopically studied in solution, the self-assembled monolayer on gold, and Langmuir–Blodgett (LB) layers on a fused quartz surface. The absorption maximum (λmax) of the OPE component in chloroform is red-shifted by 4 nm from the reference OPE derivative without the helical peptide component. The red shifts of the OPE component are also observed in the LB monolayer and bilayer compared with that of the self-assembled monolayer. The observed dipole effect of the peptide on the OPE electronic structure was quantitatively discussed with ab initio calculations. Antiparallel orientation on the dipole directions of the peptide and the OPE components is considered to explain the red shifts via the dipole effect on the electronic structure of the OPE.

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.
