2,9-Dichloro-1,10-phenanthroline

CAS 29176-55-4

2,9-Dichloro-1,10-phenanthroline combines a metal-binding nitrogen pair with nearby substituted positions that support molecular redesign. CAS 29176-55-4 can serve as a precursor to more elaborate ligands or enter a coordination assembly in its existing form. Published examples include a larger terphenanthroline architecture and a copper iodide hybrid investigated for luminescent coatings. Those applications belong to the actual derivatives and assembled structures, rather than automatically to the isolated starting reagent. The position numbers matter because changing groups near the donor region can change the surrounding space. Its story connects precise substitution with the construction of metal-containing systems, showing why a useful building block and a measured final material should be described at their own structural levels when interpreting a particular research result.
