The 28th CIMoS Seminar <br>Chirality related properties of helicene and tetrathiafulvalene materials

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] Our endeavour towards chiral molecular superconductors will be outlined.[4]

Another chirality related effect is the chirality induced spin selectivity (CISS) consisting in a preferential spin transmission through a chiral material. We will discuss helicene and tetrathiafulvalene based materials showing this property.[5]
