A new indium-phenanthroline based complex as a fluorescence sensor: Synthesis, characterization and detection of multiple analytes

Thermal deprotonation and condensation of melamine in the presence of indium(iii)chloride

“…In some of indium metal–organic compounds, the ligands alone doesn't show any photoluminescent property meaning that rather the ligand-to-metal charge transfer is responsible for the observed photoluminescence. 38 In this study, the emission band of 530, and also the calculated decay times fall in the region of similar works on indium-based complexes. 35,37,42–44 The observed luminescence of this compound is most likely due to ligand-to-metal charge transfers (LMCT) or metal-centered transitions, as the decay times are in the microsecond range.…”

“…Metal–organic complexes with indium metal centers were reported before to have photoluminescent properties. 35–38 In fact, complexes with a d 10 metal center have been considered as luminescent materials. 39 Furthermore, the luminescence and photochemistry of porphyrin and phthalocyanine complexes with group 13 metals have been reported in several studies.…”
