Crystal structures and photoluminescent properties of two d10 metal coordination polymers based on 5-aminodiacetic isophthalic acid

The effect of metalation processes on polymer morphology and conductivity properties

“…The main peaks seen at 300 nm are attributed to an intra-ligand transition π-π* backbone of the polymers, and the others appearing at around 600 nm are assigned to the mixture of the intra-ligand transition, the ligand metal charge transfer (LMCT) and the metal ligand charge transfer (MLCT). [54][55][56][57] If one of the interesting spectrums, which belongs to the P 2 -Co em complexes, is compared with P 2 , it reveals that they overlapped and shifted peaks at the 302 and 307 nm regions. These data also matche the FT-IR results (Table 2) of the imine group, where the metalated polymers have a lower frequency than the backbone of the polymers.…”

“…5) [13]. A slightly red shift of 30 nm for 1 and blue shift of 16 nm for 2 in comparison with the emission of free ligand may be assigned to the coordination of the triazole-type ligand to the metal ions [14].…”
