Abstract

Two layered zirconium phosphates containing Ru(bpy)32+ mono- or diphosphonates and diquat, {Ru(bpy)32+[1]/ZrP/DQ++} and Ru(bpy)32+[2]/ZrP/DQ++, covalently attached to the phosphate layers exhibit notable photovoltaic response (the maximum VOC, JSC, and FF were 0.093 V, 16.8 μA cm−2 and 0.33, respectively). The photocurrent spectra indicate that the photovoltaic response is due predominantly to direct photoexcitation of γ-ZrP host, Ru(bpy)32+ and diquat acting as hole and electron traps, respectively, for the charge separated state of the semiconductor.

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.
