As cut-outs from a graphene sheet, nanographenes (NGs) and graphene nanoribbons
(GNRs) are ideal cases with which to connect the world of molecules with that of bulk carbon …

Conspectus Azulene, an isomer of naphthalene, is a molecule of historical interest for its
unusual photophysical properties, including a beautiful blue color derived from the narrow …

The quest for planar sp2-hybridized carbon allotropes other than graphene, such as
graphenylene and biphenylene networks, has stimulated substantial research efforts …

Recently, a new two-dimensional allotrope of carbon (biphenylene) was experimentally
synthesized. Using first-principles calculations, we systematically investigated the structural …

Graphene nanoribbons (GNRs) are quasi‐1D graphene strips, which have attracted
attention as a novel class of semiconducting materials for various applications in electronics …

In a very recent accomplishment, the two-dimensional form of biphenylene network (BPN)
has been fabricated. Motivated by this exciting experimental result on 2D layered BPN …

Molecular nanocarbons containing heptagonal rings have attracted increasing interest due
to their dynamic behavior, electronic properties, aromaticity, and solid‐state packing …

Experimental and theoretical investigations have revealed that the chemical and physical
properties of graphene are crucially determined by their topological structures. Therefore …

Graphene turns out to be the pioneering material for setting up boulevard to a new zoo of
recently proposed carbon based novel two dimensional (2D) analogues. It is evident that …
