Abstract Phthalocyanine (PC)‐based metal–organic frameworks (MOFs) hold substantial promise for applications in energy storage, sensing, and catalysis due to their robust stability enhanced electron transfer capabilities. However, synthesizing phthalocyanine linkers with precise geometries presents a significant challenge, which limits prevalence the field. Traditional methods typically employ readily synthesized tetratopic PC realizing PC‐based MOFs. In response, study an innovative approach using ditopic ABAB‐phthalocyanine MOF linkers. The A B building blocks synthesis are deliberately designed circumvent issues of statistical condensation. These then utilized fabrication zinc‐based surface‐anchored (SURMOF) thin films. structural electronic properties these SURMOFs explored through series detailed experimental computational methods, including X‐ray diffraction, scanning microscopy (SEM), density functional theory (DFT) calculations. UV–Vis spectroscopy reveals improvements absorption, thereby enhancing material's performance light harvesting conversion. Furthermore, photodetector built this novel linker demonstrates high efficacy long‐wavelength region (780 nm), highlighting its potential cutting‐edge sensing technologies.
