This paper presents a succinct overview of recent advances of our research groups in the field of supramolecular chirogenic systems in the solution and in the solid state and consequent progress towards various functional materials having potential applications in different areas of science and technology. The phenomenon of supramolecular chirality, which is a smart combination of supramolecular chemistry and chiral science, is demonstrated with one of the most representative structural motifs amongst existing chirogenic systems, which is based upon the ethane-bridged bis-porphyrinoids. Further progress towards various functional materials is made upon preparation of different thin-films and nanostructures using the same bis-porphyrin architecture. For more practical application of functional materials chiral modification of metal surface is carried out resulting in effective asymmetric catalyst.

"Crown ethers, such as dibenzo-18-crown-6 (DB18C6) are in principle perfect building blocks to be stacked on top of each other for one-dimensional (1D) channel formation. However, in the more than 1000 publications on crown ethers in the solid state, only one case was of channel formation described, but not as main focus of research.[1] We now present a way to systematically induce the stacking of DB18C6 with the help of polyhalides, which play the roles of scaffolds via halogen bonding.[2] These compounds can be considered as ""supramolecular straws"". Using for example potassium as couter ion for triiodide for example, we obtained a solid which contains three differently filled, parallel channels in the solid state, which are arranged between the polyhalide anions. Exchanging potassium with sodium by immersion of a single crystal into NaOH solution leads to a single-crystal-to-single-crystal transformation into a compound with two channel types. This transition from a system crystallizing initially in the P2-space group to yield a compound in Pccn is only possible under these very special conditions. We will further present how the ion transport through these channels can be quantified and which process is involved in ion exchange. The role of the polyhalide anions, which cannot be replaced by other linear anions, will be emphasized as well. "
