“…Introduction of specific functionalities at the periphery of the coordinating moiety has allowed the synthesis of macrocyclic systems capable of multi-recognition, and that may be used, for example, in specific separation, [51][52][53][54] transport processes across membranes, [55,56] or activation and catalysis in ecocompatible solvents. [57] In these areas, the presence in the molecules of pendant arms (two or more) attached to the proper positions of the macrocycle framework appears particularly interesting, since it allows for the generation of a pseudo-enclosed environment suitable for modeling of supramolecular molecule-receptor systems.…”

This article aims to provide a survey of biological applications of Schiff base macrocycles and their metal complexes, with emphasis given to the synthesis of the compounds and to their uses as antibacterial and antifungal agents. The literature on the subject, published during the 2005–2019 period, is shortly reviewed. This is an informed report collecting information on the addressed topic in a concise systematic way, and can be expected to be useful as a fast literature catalogue for researchers working on this and related domains.

“…Schiff bases containing a 2-OH group are molecules that are stabilized by intramolecular hydrogen bonding. These molecules act as chelating agents for many cations (Chohan et al, 2001;Topal et al, 2007). The exchange of the OH proton with a cationic species is relatively easy.…”

There is one independent molecule in the asymmetric unit of the title compound, C 13 H 9 BF 3 NO, which crystallizes in the non-centrosymmetric space group Cc. In the molecular structure, the BF 2 -carrying ring is distorted from planarity and its mean plane makes a dihedral angle of 42.3 (1) with the 4-fluorophenyl ring. F atoms are involved in all of the short intermolecular contacts of the crystal structure, which link molecules to form chains along [001] and [010]. Structure descriptionSchiff bases containing a 2-OH group are molecules that are stabilized by intramolecular hydrogen bonding. These molecules act as chelating agents for many cations (Chohan et al., 2001;Topal et al., 2007). The exchange of the OH proton with a cationic species is relatively easy. The same is realised for the exchange of a proton by a strong Lewis acid (BF 2 group). Is such a case, the N/BF 2 interaction is much stronger than hydrogen bonding due to the high mobility of the proton. As a consequence, the BF 2 À derivatives do not lose excitation energy by vibration but fluoresce very intensively. Thus, salicaldehyde has been used several times to develop BF 2 -carrying fluorophores. These were reviewed by Ziessel and co-workers (Frath et al
