Abstract

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 , F 2 ‐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 F 2 ‐ppyPt(acac) were controlled solely by changing the N‐up and S‐up geometries. The MCPL/PL wavelengths of F 2 ‐ppyPt(acac) in solutions were varied by the ratio of the monomeric and excimeric species.
