Abstract
Systematically modulating the structural environment of solid-state materials is critical for tailoring physical-chemical interactions. Here, we demonstrated the synthesis and characteristics of three hybrid zincophosphite frameworks (NTOU-12a, -12b, and -12c) that were designed by using Hard-Soft (HSAB) principles to modulate lanthanide adsorption and luminescence. In the replacement of oxygen-donor dicarboxylate ligands with a sulfur-containing linker (2,5-thiophenedicarboxylic acid), the local coordination environment and structural chemistry were systematically modified while preserving the overall framework architecture. This substitution led to 27-42% and 32-41% decreases in uptake of Eu3+ and Tb3+ ions, respectively. By tuning the ratio of adsorbed Eu3+/Tb3+ on the title compounds, the emission color could be continuously tuned over a wide spectral range. Notably, NTOU-12a exhibited white-light emission under 254 nm excitation. These results demonstrate that rational ligand substitution provides an effective strategy for designing crystalline materials with selective lanthanide adsorption and tunable multicolor luminescence.
