Since the discovery of its facile synthesis in 2001, meso-aryl-substituted expanded
porphyrins have been developed as a new class of azaannulenes in light of their facile …

Conspectus Organic glasses containing chromophores with large first hyperpolarizabilities
(β) are promising for compact, high-bandwidth, and energy-efficient electro-optic devices …

Density functional theory calculations have been performed for alkali metal encapsulated
X12Y12 nano-cages (X= B, Al and Y= N, P) to evaluate their stability, boundary crossing …

The role of aromaticity in porphyrinoids is a current subject of debate due to the intricate
structure of these macrocycles, which can adopt Hückel, Möbius and even figure-eight …

The unique properties of chemical materials are usually related to the topology and size of
their constituent unit. Inspired by a previous report on the synthesis of a separable catenane …

Meso‐aryl expanded porphyrins present a structural versatility that allows them to achieve
different topologies with distinct aromaticities. Several studies appeared in the literature …

The electronic and non-linear optical (NLO) properties of alkaline earth metals (Be, Mg, Ca)
doped Be 12 O 12 and Mg 12 O 12 nanocages were investigated. For each nanocage, both …

As long as 50 years ago theoretical calculations predicted that Möbius annulenes with only
one π surface and one edge would exhibit peculiar electronic properties and violate the …

The optical absorption properties of (poly) aromatic hydrocarbons occluded in a nanoporous
environment were investigated by theoretical and experimental methods. The carbonaceous …

The electrides have a very special electronic structure with diffuse excess electrons not
localized on any specific atom. Such systems are known to have huge electronic nonlinear …
