Chirality manifests itself in many areas of physics, chemistry and biology, where objects or materials can exist in two non super-imposable forms, one being the mirror image of the other. 1 Introduction of chirality into conducting systems is a topic of much current interest as it allows the preparation of multifunctional materials in which the chirality might modulate the structural disorder or expresses its influence through the electrical magneto-chiral anisotropy effect. 2 The access to various chiral electroactive precursors for molecular conductors is therefore of paramount importance. 3 In the same time, the most distinctive manifestation of chirality in chemistry is in the optical activity of chiral compounds, expressed as optical rotation or circular dichroism (CD). Additionally, when a chiral compound is emissive, circularly (CPL) can be expected to occur. In this lecture several chiral conducting or photoactive systems will be discussed.
