The sensing performance of MeOBnSPO for Cu2+ was achieved with a ‘turn-on’ fluorescent detection in acetonitrile. The results demonstrated that MeOBnSPO possessed high selectivity towards Cu2+ with a 10-fold enhancement in fluorescence intensity (λem = 544 nm) and high sensitivity at the micromolar concentration. The limit of detection was calculated to be 19.1 nM. Evidence for the ring opening reaction and 1:1 stoichiometric complexation of MeOBnSPO to Cu2+ was proven by 1H NMR titration, FT-IR, MS, and Job analyses. Moreover, a drastic change in colour from colourless to bright yellow could provide naked-eye detection for Cu2+ with rapid response. The viable test strips of MeOBnSPO were also developed for Cu2+ colorimetric detection in mixed acetonitrile – H2O (50:50 v/v).

We also perform a variety of 1H NMR dilution studies and in-silico modelling to further explore the roles of intermolecular hydrogen bonding and lipophilicity within aggregate formation and antimicrobial efficacy. Finally, we perform haemolysis and Galleria mellonella toxicity assays to establish the potential of these compounds to undergo further development as antibiotic agents.

Upon coordination of sodium cations to all sulphonate groups of the macrocycle the 3-D coordination polymer is formed. The C8S adopts circular pleated loop conformation and macrocyclic molecules are assembled into stacks stapled by coordination to multiple sodium cations. The arrangement of the metallo-supramolecular assembly is pseudo-hexagonal. In the presence of organic cation berberine, the host-guest complex is favoured. Macrocycle adopts conformation without a substantial internal cavity with two of the benzenesulfonate groups being inclined towards the centre of the molecule. One host binds eight berberine guests in the grooves and clefts of the molecular surface of the macrocycle. C8S is a suitable host for berberine in the solid state, and such crystallisation-driven host-guest complexation has potential in expanding the library of berberine crystal forms.

Neutral 1,4-dicyanobutane-based alkylated DCB_ProP[5]A is found to show higher binding energy when compared to the other three host-guest macrocycles. These complexes are largely stabilised by non-covalent interactions, which are ascertained through NCI and QTAIM analyses. Furthermore, the second-order perturbation energy of NBO analysis show that LP (N) – σ*(C-H) interactions predominate in DCB_ProP[5]A complex. Particularly, alkyl substituents (-methyl, -ethyl and -propyl) are playing a vital role in stabilising the host-guest complexes. In summary, the present work not only exhibits an efficient strategy to build a new family of alkylated P[5]A inclusion complexes but also providing deeper understanding on various non-covalent interactions towards 1,4-dicyanobutane (DCB) guest molecules inside the host environment.
