چکیده
We present the characterisation of a hydrogel forming family of benzene 1,3,5-tricarboxamide (BTA) aromatic carboxylic acid derivatives. The simple, easy to synthesise compounds presented here exhibit consistent gel formation at low concentrations through the use of a pH trigger.

Some benzene-1,3,5-tricarboxamide (BTA) monomers derived from (l) α-amino esters self-assemble into long rods at millimolar concentrations, and display a strong chiral amplification effect. These rods are in competition with dimeric species.
متن کاملSupramolecular polymerization in water harnessing both hydrophobic effects and hydrogen bond formation.
The formation of supramolecular polymers in water through rational design of a benzene-1,3,5-tricarboxamide (BTA) motif is presented. Intermolecular hydrogen bonding and hydrophobic effects cooperate in the self-assembly into long fibrillar aggregates. Minimal changes in molecular structure significantly affect the internal packing of the aggregates.
متن کاملSupramolecular polymerisation in water; elucidating the role of hydrophobic and hydrogen-bond interactions.
Understanding the self-assembly of small molecules in water is crucial for the development of responsive, biocompatible soft materials. Here, a family of benzene-1,3,5-tricarboxamide (BTA) derivatives that comprise a BTA moiety connected to an amphiphilic chain is synthesised with the aim to elucidate the role of hydrophobic and hydrogen-bonding interactions in the self-assembly of these BTAs. ...
متن کاملExternal electric field reverses helical handedness of a supramolecular columnar stack.
Benzene-1,3,5-tricarboxamide (BTA) molecules self-assemble into one-dimensional columnar structures that possess a macrodipole moment along the stacking direction. Application of an external electric field on their liquid crystalline (LC) phase consisting of aligned stacks leads to a net polarization whose sign can be reversed by changing the direction of the field. Atomistic molecular dynamics...
متن کاملDynamic diversity of synthetic supramolecular polymers in water as revealed by hydrogen/deuterium exchange
Numerous self-assembling molecules have been synthesized aiming at mimicking both the structural and dynamic properties found in living systems. Here we show the application of hydrogen/deuterium exchange (HDX) mass spectrometry (MS) to unravel the nanoscale organization and the structural dynamics of synthetic supramolecular polymers in water. We select benzene-1,3,5-tricarboxamide (BTA) deriv...
