Overview

Randomized trial shows the effects of fluorination on structural disorder and optical properties in cadmium hybrids, highlighting important implications for material design.

Key Points

To understand how fluorination and halide mixing affect structural disorder and entropic changes in 2,2-difluoroethylammonium cadmium hybrids.
Conducted structural single-crystal X-ray diffraction studies to assess positional disorder.
Performed differential scanning calorimetry to analyze entropy changes related to phase transitions.
Utilized IR spectroscopy and DFT calculations to evaluate intermolecular interactions and structural changes.
Fluorination increases intermolecular F···F interactions, resulting in enhanced rigidity.
Significant entropy changes during phase transitions indicate complex ordering mechanisms (including hydrogen bond reorganization).
Optical properties are tunable based on halide substitution and structural rigidity.
