Biological applications of sumanene buckybowl molecule have been widely discussed over the years yet remain still unexplored experimentally. On the other hand, creating cyclodextrin-containing supramolecular assemblies was demonstrated to be a powerful tool in terms of designing effective systems for medicinal chemistry purposes. Here, we show that sumanene molecule exclusively forms 1:1 host-guest complexes with γ-cyclodextrin (γCD) or (2-hydroxypropyl)-γ-cyclodextrin (HP-γCD), as revealed by extensive spectroscopic studies supported with density functional theory (DFT) computations. Based on our preliminary biological studies, we discovered that the formation of such complexes resulted in the improvement of anticancer properties of sumanene, expressed by high cell viabilities in vitro of healthy human mammary fibroblasts (HMF) together with low viabilities of human breast adenocarcinoma cells (MDA-MB-231). Improved pharmacokinetic (ADME-Tox) properties for sumanene@γCD and sumanene@HP-γCD complexes in comparison to native sumanene were also supported by in sillico modeling studies. This work provides the method how to focus the cytotoxic action of sumanene toward cancer cells using supramolecular assembly strategy, paving the way to the further exploration of biological properties of sumanene-containing supramolecular systems with bioactive features and applications of this buckybowl in general.

Article Synopsis
- A sumanene monolayer with a unique Kagome-like lattice features two flat bands and two Dirac cones, which can be designed using carbon clusters.
- First-principles simulations show that surface charge doping can effectively adjust the Fermi level between these bands, allowing for the transformation of the semiconducting monolayer into a semimetal using Li/Na/K atoms.
- This doped sumanene exhibits high theoretical storage capacity, rapid charge capability, and exceptional structural stability, making it an attractive anode material for alkali-metal batteries.

Doping the π-frameworks of polycyclic aromatic hydrocarbons (PAHs) with main-group elements is a powerful strategy to manipulate optoelectronic properties. Herein, the benzylic carbons of π-bowl sumanene are replaced with chalcogens (S, Se, and Te) and trivalent phosphorus (P), affording a series of P-doped heterosumanenes (HSEs). The lone-pair electrons of the P-dopant endow these HSEs with pronounced affinity toward transition metals (Au, Pt, and Pd).

The design of novel low-dimensional carbon materials is at the forefront of modern chemistry. Recently, on-surface covalent synthesis has emerged as a powerful strategy to synthesize previously precluded compounds and polymers. Here, we report a scanning probe microscopy study, complemented by theoretical calculations, on the sequential skeletal rearrangement of sumanene-based precursors into a coronene-based organometallic network by stepwise intra- and inter-molecular reactions on Au(111).

Aromatic infrared bands (AIBs) dominate the mid-infrared spectra of many galactic and extragalactic sources. These AIBs are generally attributed to fluorescence emission from aromatic molecules. Unified efforts from experimentalists and theoreticians to assign these AIB features have recently received additional impetus with the launch of the James Webb Space Telescope (JWST) as the Mid-InfraRed Instrument (MIRI) delivers a mid-IR spectrum with greatly increased sensitivity and spectral resolution.
