Sergeants‐and‐Soldiers Principle in Chiral Columnar Stacks of Disc‐Shaped Molecules with C₃ Symmetry

Abstract

Extremely effective cooperative effects operate during the formation of chiral stacks of C3‐symmetrical molecules in alkane solvents (a molecule is depicted on the right). The sergeants‐and‐soldiers principles as well as chiral solvation lead to a preferred helical sense in the columnar aggregates. The amplification of chirality in dynamic systems shows the precision in aggregation.

Self-Sorting Chiral Subcomponent Rearrangement During Crystallization

“…Investigations of the expression of chiral information during self-organization have led to the development of a remarkable array of structures and functions, 17,19,[56][57][58][59][60] from the sergeantsand-soldiers principle 61,62 to a light-powered rotor. 63,64 The chiral information expressed by the system comprising helicate 1 and its diastereomers allowed us to track separately the reversible ligand-exchange and imine-exchange processes occurring within this mixture of structures.…”

Columnar self-assembly of N,N′,N′′-trihexylbenzene-1,3,5-tricarboxamides investigated by means of NMR spectroscopy and computational methods in solution and the solid state

“…[9,10] Derivatives of BTA have been investigated as MRI contrast agents, [11] metal complexation agents [12] and utilized in drug-delivery systems. [13] Investigations of BTA-based self-assemblies have focused on the effects of the aliphatic chains, [14,15] introduction of elements of chirality [16] and substitutions on the central aromatic moiety. [17][18][19] The aggregation process of BTA units and their charge transport properties have been investigated by means of quantum chemical calculations.…”

A dynamic supramolecular polymer with stimuli-responsive handedness for in situ probing of enzymatic ATP hydrolysis

“…Typical designs of helical assemblies consist of optically active monomers, which bias the handedness during the (supramolecular) polymerization process [8][9][10][11][12][13][14][15][16][17][18][19] . In this respect, helicity induction in racemic or achiral assemblies constructed from achiral monomers through non-covalent interactions with the chiral guest molecules is an alternative, synthetic strategy [20][21][22][23][24][25][26] . This host-guest design for helical motifs not only provides new opportunities to investigate mechanistic details of supramolecular chirality, but also offers practical chirotechnological applications.…”
