A comprehensive study of the photophysical interactions occurring in tris-porphyrin and tetrakis-porphyrin arrays 1 and 2 has been undertaken. The arrays consist of porphyrins with quinoxaline units fused at the β,β′-pyrrolic faces of the macrocycle. The linkage geometry is such that these arrays resemble the arrangement of chromophores that constitute natural photosynthetic reaction centres (PRCs). Selective metallation of the terminal chromophores of the arrays with Zn(II) and Au(III) allows directional electron and energy transfer processes to occur. The results show that excitation at any chromophore of the arrays leads to efficient charge transfer across the length of the arrays, distances of 35 and 50 Å for 1 and 2, respectively. Charge recombination is several orders of magnitude slower in both cases. The excellent performance of these arrays is attributed in part to the use of quinoxalinoporphyrins. Linked appropriately, π-system-fused porphyrins can exhibit strong electronic communication in the excited state, whilst being effectively insulated in the ground state. As such, arrays of these porphyrins might find use as components of photovoltaic devices.

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.
