DESCRIPTION:Prof. Dr. Prince Ravat\, Prof. Dr. Oliver Dumele\, Universitä
 t zu Köln\n\nTwisting Light and Spin: Helicenes as Multifunctional Molecu
 lar Spring\n\nHelicenes\, with their characteristic corkscrew-shaped geome
 try\, serve as versatile molecular scaffolds for constructing configuratio
 nally robust chiral functional materials through precise structural design
 . Ravat group focuses on leveraging this unique architecture to control el
 ectronic and (chir)optical properties at the molecular level. \nDumele gro
 up has employed helicenes as building blocks for two-dimensional covalent 
 organic frameworks (COFs)\, uncovering their crystalline order arising fro
 m homochiral (enantiopure) or racemic packing modes. This work has led to 
 an unexpected discovery — the same [5]helicene can act as a photochemica
 l spin-state switch\, enabling reversible control of the magnetism with li
 ght.
