Article Synopsis
- The research involves creating trigonal planar Cu(I) iodide complexes using specific disilane ligands and studying how methyl group positions on the pyridine ring impact their structure and properties.
- Characterization methods included NMR, elemental analysis, and X-ray diffraction, revealing different conformations of ligand coordination with Cu(I) that affected emission colors—blue-green for one complex and green-yellow for another.
- The complexes demonstrated significant light emission properties, with high quantum yields and thermally activated delayed fluorescence at room temperature, showing unique optical behaviors analyzed through advanced computational methods.
A thermoresponsive structural change based on a disilane-bridged bis(pyridine) ligand and CuI is reported. Single-crystal X-ray analysis revealed that there are two polymorphs in the Cu(I) complex: octanuclear copper(I) complex at 20 °C and 1D staircase copper(I) polymer complex at -173 °C. The formation of these polymorphs is due to the flexibility of the ligand.
