Can aromaticity be a kinetic trap? Example of mechanically interlocked aromatic [2-5]catenanes built from cyclo[18]carbon

Abstract

Aromaticity serves as a kinetic trap for mechanically interlocked cyclo[18]carbon rings.

Reply to the Comment on “Realization of Lewis Basic Sodium Anion in the NaBH3− Cluster”

“…Correspondence deciphering chemical bonding in non-trivial clusters, [34][35][36][37][38][39][40][41][42][43][44][45][46][47] molecules [48,49] and solids. [50][51][52][53][54] Advantage of the AdNDP method is in its capability to reproduce illustrative Lewis-like structure accepted by broad chemical audience while QTAIM approach is meaningful for those having solid background in theoretical chemistry.T herefore,weemphasize that AdNDP is more appropriate for studying the bonding picture in such compounds.I ta lso worth mentioning that that AdNDP results are also almost independent of method and basis set.…”

Remarkable Size Effect on Photophysical and Nonlinear Optical Properties of All‐Carboatomic Rings, Cyclo[18]carbon and Its Analogues

“…Cyclo [18]carbon (C 18 ), a closed-loop polyyne of 18 sp-hybridized carbon atoms joined together, is one of the hottest molecule recently. Due to its unique molecular geometry and electronic structure, C 18 has quickly attracted extensive attentions from chemists after being generated and observed in condensed phase in 2019 1 and soon received wide investigations [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18] . Our group has also made a series of theoretical studies on it, including aromaticity, optical properties, intermolecular interaction, vibrational spectra, and so on [19][20][21][22][23] .…”

“…As an extension to this concept, spherical‐like structures also enable similar properties related historically to π‐planar species, among monolayers, expanded molecules, and other species, which can be explored in different metallic clusters …”
