Supramolecular self-assembly has allowed the synthesis of beautiful and complex molecular architectures, such as cages, macrocycles, knots, catenanes, and rotaxanes. We focus here on porous organic cages, which are molecules that have an intrinsic cavity and multiple windows. These cages have been shown to be highly effective at molecular separations and encapsulations. We investigate the possibility of complexes where one cage sits within the cavity of another. We term this a `nested cage' complex. The design of such complexes is highly challenging, so we use computational screening to explore 8712 different pair combinations, running almost 0.5M calculations to sample the phase space of the cage conformations. Through analysing the binding energies of the assemblies, we identify highly energetically favourable pairs of cages in nested cage complexes. The vast majority of the most favourable complexes include the large imine cage reported by Gawronski and co-workers using a [8+12] reaction of 4-tert-butyl-2,6-diformylphenol and cis,cis-1,3,5-triaminocyclohexane. The most energetically favourable nested cage complex combines the Gawronski cage with a dodecaamide cage that has six vertices, which can sit in the six windows of the larger cage. We also identify cages that have favourable binding energies for self-catenation.

Purpose – The purpose of this paper is to create a textile material which shows antibacterial activity with resistance to environmental conditions by using volatile active agent inclusion complex and self-assembly method. Design/methodology/approach – An inclusion complex of carvacrol and β-CD is generated by kneading method and deposited on the cotton fabrics by using a nanofabrication method named as layer-by-layer (LbL) deposition method. Three different concentration of CD and CD:Car aqueous solutions were deposited on cotton fabrics. Attenuated total reflectance Fourier transform infrared spectroscopy (FTIR-ATR), scanning electron microscopy (SEM), antimicrobial efficacy test of fabrics against washing and some physical tests (water vapor permeability, air permeability) were performed on the fabrics before and after the treatment with CD to evaluate the effect of the LbL process on cotton fabric properties. Findings – The results showed that the coated fabrics with CD/CD:Car multilayer films enhanced the antimicrobial efficacy of cotton fabrics against to Klebsiella pneumonia and Staphylococus aureus bacteria. Air and water vapor permeability properties of the cotton fabric effected after the LbL deposition process sure enough. With SEM and FTIR-ATR analysis the CD:Car complex presence were verified. The durability of antibacterial properties were analyzed after one and ten washing (40°C and 30 min) cycles. Originality/value – This work provides a novel and simple method for CD and inclusion complex of carvacrol film deposition by self-assembly method on cotton fabrics and their application onto cotton fabrics to gain antibacterial property.
