Conjugated polymers, comprising fully π‐conjugated systems, present a new generation of
heterogeneous photocatalysts for solar‐energy utilization. They have three key features …

Conspectus Negatively curved carbons are theoretical carbon allotropes as proposed by
embedding heptagons or octagons in a graphitic lattice. Unlike five-membered rings in …

The synthesis of a carbon nanobelt, comprising a closed loop of fully fused edge-sharing
benzene rings, has been an elusive goal in organic chemistry for more than 60 years. Here …

Organic molecular semiconductors have been paid great attention due to their advantages
of low-temperature processability, low fabrication cost, good flexibility, and excellent …

Non‐alternant non‐benzenoid π‐conjugated polycyclic hydrocarbons (PHs) are expected to
exhibit very different electronic properties from the all‐benzenoid PHs. Herein, we report the …

Defective nanographenes containing joined pentagons and heptagons exhibit striking
physicochemical properties from both experimental and theoretical perspectives compared …

The synthesis and X-ray crystal structure of the first member of the carbon nanobelt family is
reported.[12] Carbon nanobelt ([12] CNB) was originally obtained from a nickel-mediated …

Efficient polymer photocatalysts that mimic natural photosynthesis to generate H2 through
the visible‐light‐promoted splitting of water are ideal systems for the conversion of solar …

Non‐alternant topologies have attracted considerable attention due to their unique
physiochemical characteristics in recent years. Here, three novel topological …

Negatively curved nanographene (NG) 4, having two heptagons and a [5] helicene, was
unexpectedly obtained by aryl rearrangement and stepwise cyclodehydrogenations. X-ray …
