Non-classically Controlled Sign in a 1.6 Tesla Magnetic Circularly Polarized Luminescence of Three Pyrenes in a Chloroform and a PMMA Film

Molecular pyrene, 1-hydroxylpyrene, and 2-hydroxypyrene in chloroform and embedded in poly(methyl methacrylate) film reveal mirror-image magnetic circularly polarized luminescence (MCPL) when south (S)-up or north (N)-up direction of the longitudinal external magnetic field of 1.6 T to unpolarized incident light (Faraday geometry) is employed. The |gMCPL| magnitude is on the order of 10−3 T−1 in 374–416 nm. The sign of MCPL is controlled by the S-up and N-up geometry and by the position (1- or 2-) of the hydroxy group. Three monomeric optically inactive pyrenes in chloroform and poly(methyl methacrylate) film reveal clear mirror image magnetic circularly polarized luminescence (MCPL) under 1.6 T magnetic field. The MCPL sign is fully controlled by switching the north-up and south-up magnetic field, and, interestingly, depends on the 1- or 2-position of an OH group on the pyrene ring.
