A theoretical and experimental study on meridional-facial isomerization of tris(quinolin-8-olate)aluminum (Alq3)

23 July, 2014 - 21:17

Dalton Trans., 2014, Advance Article
DOI: 10.1039/C4DT01121J, CommunicationI. Iwakura, H. Ebina, K. Komori-Orisaku, Y. Koide
The rationale behind the stereospecific synthesis of a facial isomer of tris(quinolin-8-olate)aluminum (Alq3) is studied by density functional theory (DFT) calculations, which predict the favourable influence of an H3O+ ion on the distribution ratio between a meridional and a thermodynamically unstable facial isomer.
