The role of the structural similarity in individual components on self-assembly process multi-component systems was studied by analysing gelation properties chiral gels with structurally similar (enantiomers) and non-similar donor or acceptor moieties. enantiomers, mixed donor-acceptor compounds were analysed various solvents. Analysis mechanical strength revealed that stronger compared to other mesitylene; however, a reverse trend observed for thermal stability.

Abstract In this work, a core‐substituted NMI‐conjugated dipeptide (4MNLV) was extensively studied in mixed solvent systems to explore the polarity effect on self‐assembly pattern and their photophysical property. 4MNLV adopted J‐ or H ‐ type aggregation depending upon index of system chosen. The process achieved through anti‐solvent effect. UV‐vis study suggested that if stock solution diluted with relatively more polar (compared solvent), then acquired by showing red‐shift absorption maxima (λ max ). Conversely, when less solvent, H‐ observed, where blue shift λ noticed. emission spectra lifetime self‐assembled materials were also influenced chosen system. chirotopic behaviour these CD spectroscopy. Morphological indicated formation helical nanofibrillar structures. bright green fluorescence highly biocompatible naphthalimide‐peptide conjugate used for cell imaging application, indicating its futuristic scope.

The formation of a robust, self-healing hydrogel novel pyrene-appended dipeptide, Py-E-A (L-Glutamic acid short as E; L-Alanine A) is demonstrated. Detailed studies suggest that nanoscopic fibers with length several micrometers have formed by chiral self-organization gelators. Additionally, live human PBMCs imaging shown using the fluorophore.
