Recent Advances in Dimeric Cycloparaphenylenes as Nanotube Fragments

Abstract

Since the advent of cycloparaphenylenes (CPPs) in 2008, the chemical synthesis of more complicated molecular systems with curved π-surface was vigorously sought after, giving rise to a plethora of new, exciting molecules with various topology and function. Herein, this Synpacts article serves to briefly summarize recent examples of carbon nanohoop dimers, while highlight three examples as nanotube fragments. The synthesis, isomerization, photophysical properties and host-guest chemistry will be discussed.

Stepwise deprotonation of truxene: structures, metal complexation, and charge-dependent optical properties

“…Since the discovery of C 60 -fullerene in 1985, 1 molecular nanocarbons have attracted enormous attention in fundamental chemistry and materials science. Over the decades, a wide variety of molecular nanocarbon architectures with different sizes and topologies have been synthesized with tunable chemical and physical properties, [2][3][4][5][6][7][8][9] which greatly expands their applications in energy storage, optoelectronic devices, and superconductors. [10][11][12] In particular, the fusion of ve-membered rings into the hexagonal carbon framework can cause changes in structure and reactivity.…”
