Atomically accurate site-specific ligand tailoring of highly acid- and alkali-resistant Ti(iv)-based metallamacrocycle for enhanced CO₂ photoreduction.

ABSTRACT: Skillfully engineering surface ligands at specific sites within robust clusters presents both a formidable challenge and a captivating opportunity. Herein we unveil an unprecedented titanium-oxo cluster: a calix[8]arene-stabilized metallamacrocycle (Ti₁₆L₄), uniquely crafted through the fusion of four "core-shell" {Ti₄@(TBC[8])(L)} subunits with four oxalate moieties. Notably, this cluster showcases an exceptional level of chemical stability, retaining its crystalline integrity even when immersed in highly concentrated acid (1 M HNO₃) and alkali (20 M NaOH). The macrocycle's surface unveils four specific, customizable μ₂-bridging sites, primed to accommodate diverse carboxylate ligands. This adaptability is highlighted through delibera
