C hiral compounds absorb circularly polarized light of opposite sense to different extents. This property, commonly known as circular dichroism, CD, is closely related to the optical rotatory dispersion of the compound under study, and has been extensively applied to the study of chiral compounds[1, 2]. On the other hand, very little information is available concerning the preferential emission of circularly polarized light of one sense over that of the opposite sense from chiral luminescent compounds. The scarcity of data about circularly polarized luminescence, CPL, is probably due to lack of suitable instrumentation for the measurement of small amounts of circularly polarized light present in a large background of unpolarized luminescence. Indeed, the only CPL data available are of a few substances which exhibit an exceptionally high degree of circular polarization in their emitted light [3, 4].
