Abstract

The magnetic circularly polarized luminescence (MCPL) and photoluminescence (PL) spectra of achiral (2,3,7,8,12,13,17,18-octaethylporphyrinato)platinum(II), PtOEP, and [2-(4',6'-difluorophenyl)pyridinato-N,C^2' ]platinum(II) acetylacetonate-O,O, F₂ -ppyPt(acac), in toluene and dichloromethane solutions were recorded under an external magnetic field of 1.6 T with N-up and S-up Faraday geometries. The MCPL signs of PtOEP and F₂ -ppyPt(acac) were controlled solely by changing the N-up and S-up geometries. The MCPL/PL wavelengths of F₂ -ppyPt(acac) in solutions were varied by the ratio of the monomeric and excimeric species.

Keywords: chiral; luminescence; magnetic circularly polarized luminescence (MCPL); platinum (Pt); porphyrinoid.
