Herein, the role of molecular engineering on optoelectronic properties antimony corroles with two distinct β ‐substituents and different oxidation states is studied. Insertion a strong electron‐withdrawing SCN group bi‐pyrrole unit corrole increases dipole moment. Consequently, dielectric constant enhanced by up to threefold, reaching value 8 for antimony(V) tetra(thiocyano)corrole, significantly higher than any solution‐processable organic semiconductor reported date. Moreover, this SCN‐substituted molecule also exhibits an increased charge carrier mobility at least orders magnitude. A combination suitable metallic state substitution crucial in defining absorption, mobility, constant, all which impact photovoltaic performance. The fluorescence quantum yield champion 300%, lifetime extended twofold, indicating fewer nonradiative recombination pathways or lower degree disorder. single‐component photodetectors white light responsivity as high 10 W −1 , ranking among best donor‐based semiconductors, solar cell fabricated from tetra(thiocyano)corrole that open‐circuit voltage 0.7 V, three times poly(3‐hexylthiophene) (P3HT)‐based devices, are demonstrated.

Abstract Electrochemical water oxidation with single atom catalysts (SACs) has garnered immense interest because of their high utilization, extraordinary activity, and elucidation the reaction mechanism. In SACs, while atomic sites offer active centers for substrate binding intermediates, interaction solid support is crucial stabilization enhancement catalytic activity. Coordinated elements surrounding site create a ligand‐like environment that influences electrochemical properties. As result, tuning coordination SACs allows modulation oxygen evolution (OER) light this, question arises: What role in stabilizing atoms (SAs) controlling activity during oxidation? This review addresses this using recent examples. Spectroscopic characterizations density functional theory (DFT) calculations provide direct answer: exhibit strong interactions via neighboring atoms, influencing OER
