Emerging applications of carbon nanohoops

Strain visualization for strained macrocycles

“…Macrocyclic strain is leveraged in chemical biology for bioorthogonal reactivity 1,2 and in polymer chemistry for ring opening metathesis. 3,4 Additionally, graphitic macrocycles, such as carbon nanohoops, 5 have enhanced solubility, 6 remarkable photophysical properties, 7,8 and reactivity [9][10][11][12] that all arise from strain. These attributes, and improvements in methods for their synthesis, [13][14][15][16] have caused a renewed interest in strained macrocyclic molecules.…”

Effect of curvature and placement of donor and acceptor units in cycloparaphenylenes: a computational study

“…20 However, red-emitting CPPs that retain enhanced solubility and brightness may be desirable as they show promise in applications where aggregation is problematic, such as spin coated thin lm electronics or biomolecule conjugation. 21,22 By incorporating electronic modulating units into CPPs we not only test strain effects on these units, but also seek useful targets for redemitting nanohoops. Indeed, red-emitting CPPs have been obtained with this approach, however, only three acceptor units have been tested to date.…”

Synthesis of cycloiptycenes from carbon nanobelts

“…The bottom-up synthesis methods using small molecules having substructures of nanocarbons, or so-called molecular nanocarbons, have attracted much attention. [6][7][8][9][10][11] Carbon nanobelts (CNBs) are molecular nanocarbons having partial structures of CNTs. In a CNB, all benzene rings are fused together to form a tubular structure.…”
