The powerful electron accepting ability of fullerenes makes them ubiquitous components in biomimetic donor–acceptor systems that model the intermolecular transfer processes Nature's photosynthetic center. Exploiting perylene diimides (PDIs) as cyclic host for noncovalent recognition is unprecedented, part because archetypal PDIs are also deficient, making dyad assembly formation electronically unfavorable. To address this, we report strategic design and synthesis a novel large, macrocyclic...
Alpha-cyclodextrin based anion receptors functionalised with pendant arms containing halogen and hydrogen bond donor motifs display selective association of perrhenate in aqueous media at neutral pH. NMR ITC binding investigations reveal the bonding receptor to be superior host.
A rotaxane host system containing a novel halogen bonding (XB) 5-iodo-1,2,3-triazole functionalised pyridinium motif, within its axle component, has been prepared via ring closing metathesis reaction, using chloride as template. Proton NMR titration experiments, in competitive 1 : CDCl3-CD3OD solvent media, showed the XB selectively bound halides over larger, more basic oxoanions. An all hydrogen proto-triazole analogue was also prepared, which stark contrast demonstrated reversal anion...
We report a water-soluble N@C<sub>60</sub> derivative and investigate its use as spin probe for Cu(<sc>ii</sc>) ions.
Fullerene dyads bridged with perfluorinated linking groups have been synthesized through a modified arc-discharge procedure. The addition of Teflon inside an reactor leads to the formation dyads, consisting two C60 fullerenes by CF2 groups. incorporation bridging containing electronegative atoms lead different energy levels and new features in photoluminescence spectrum. A suppression singlet oxygen photosensitization indicated that radiative decay from singlet-to-singlet state is favoured...
An N@C60-containing C60 tetramer was synthesized by quadruple 1,3-dipolar cycloaddition (Prato) reaction. This molecule demonstrates the N@C60 qubit's ability to form covalently linked arrays. Furthermore, it provides a promising scaffold with which measure multiple qubit-qubit interactions; must be well characterized for functioning quantum information processing architecture.
N@C 60 is a paramagnetic endohedral fullerene species comprised of single nitrogen atom incarcerated within C carbon cage. Shielding the from external environment results in extremely long relaxation times its electron spin (T 1 = 0.375 ms, T 2 0.25 ms). This provides molecule with very sharp EPR signal, which undergoes observable dipolar broadening presence other species, suggesting that derivatives would be ideal candidates as probes for biological applications. 2–4 In order this to...
