Abstract:
The π-extension of carbon nanorings towards ultrashort carbon nanotubes (CNTs) is a great challenge for synthetic chemists. Herein, we report the synthesis, characterization, and properties of a nanographene-embedded carbon nanoring (NECR) by a direct zipper method. In this approach, a long linear phenyl chain is fused onto the CPP backbone by a simple Scholl reaction, similar to zipping two pieces of fabric together. Its photophysical properties were studied by UV-vis and photoluminescence spectroscopy. The potential application of NECR in electron-transport devices were further investigated.

π Molecular Orbitals of 1,3-Butadiene
The simplest conjugated diene is 1,3-butadiene: a four-carbon system where each carbon is sp2-hybridized and has an unhybridized p orbital that contains an unpaired electron. According to molecular orbital theory, atomic orbitals combine to form molecular orbitals such that the number...

Structure of Conjugated Dienes
Conjugated dienes are compounds characterized by the presence of alternating double and single bonds. In a conjugated system like 1,3-butadiene, the unhybridized 2p orbital on each carbon overlaps continuously, allowing the π electrons to be delocalized across the entire molecule. In contrast, this type of overlap does not occur in cumulated and isolated dienes, such as 2,3-pentadiene and 1,4-pentadiene, respectively. Instead, the π electrons remain localized between the double...
