Halogenation triggering rules in hybrid materials for fluorescence and dielectric phase transitions

Three hybrid materials, (TMBPA)CdCl 2 Br (TMBPA-ClBr), (TMBPA) 2 CdBr 4 (TMBPA-Br), and (TMIPA) 2 CdI 4 (TMIPA-I), which exhibit dielectric and excellent photoluminescence properties, and the phase-transition temperature is controlled by the halogen modulation effect.
