Bioactive hydrogels based on the self-assembly of tripeptides have attracted great interest in recent years. In particular, the search is active for sequences that are able to mimic enzymes when they are self-organized in a nanostructured hydrogel, so as to provide a smart catalytic (bio)material whose activity can be switched on/off with assembly/disassembly. Within the diverse enzymes that have been targeted for mimicry, hydrolases find wide application in biomaterials, ranging from their use to convert prodrugs into active compounds to their ability to work in reverse and catalyze a plethora of reactions. We recently reported the minimalistic l-His–d-Phe–d-Phe for its ability to self-organize into thermoreversible and biocatalytic hydrogels for esterase mimicry. In this work, we analyze the effects of terminus modifications that mimic the inclusion of the tripeptide in a longer sequence. Therefore, three analogues, i.e., N-acetylated, C-amidated, or both, were synthesized, purified, characterized by several techniques, and probed for self-assembly, hydrogelation, and esterase-like biocatalysis. This work provides useful insights into how chemical modifications at the termini affect self-assembly into biocatalytic hydrogels, and these data may become useful for the future design of supramolecular catalysts for enhanced performance.

This article describes the properties of molecular nanowires as electrical conductors. It begins by defining a molecular nanowire and describing a specific example of a molecular nanowire, along with the concept of molecular nanowire self-assembly. It then considers how molecular nanowires are realized in the laboratory as well as the relationships between these methodologies, the systems that are produced and some experiments being performed on them. It also looks at the different kinds of molecules, electrodes and linkers out of which molecular nanowires are being or may be constructed; the Landauer approach to electrical conduction in molecular nanowires; the principles and limitations of ab-initio and semi-empirical modelling of molecular nanowires in the context of electrical conduction; and four specific experimental systems and the extent to which their observed behavior has been understood theoretically. The article concludes with a summary of key issues for the future development of the field.
