Abstract

The flexible Schiff-base compound 2,2′-((1,4-phenylenebis-(methylene))bis(sulfanediyl))bis(N-(pyridin-4-ylmethylene)aniline) (1; pbbpa) has been synthesized by a two-step synthetic procedure and characterized by elemental analysis, infrared (IR) spectroscopy, powder X-ray diffraction (PXRD) pattern and single crystal X-ray diffraction (SCXRD) technique. The compound exhibits electrical conductivity in the semiconducting region, as revealed by band gap calculation and further confirmed by density functional theory (DFT) computations. Interestingly, the compound formed a Schottky interface with aluminum (Al) metal, which is supported by the impedance spectroscopy (IS)-based network analysis. Besides, SCXRD of compound 1 reveals the formation of a one-dimensional (1D) water chain encapsulated by the hydrogen bonded supramolecular network.

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.
