This work provides an overview of the recent advances in the field of two-photon absorbing
chromophores active in the short-wavelength infrared (SWIR) spectral range. Herein the …

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 …

Technologies for the creation of topological carbon nanostructures have greatly advanced
synthetic organic chemistry and materials science. Although simple molecular nanocarbons …

The first synthesis of a cyclic oligophenylene possessing a radial π system was reported in
2008. In the short period that has elapsed since, there has been an ever-increasing level of …

In this paper, we theoretically explore the physical mechanism of the fluorescent origin and
chiral nature of Möbius carbon nanobelts. The electron–hole recombination is promoted by …

Aromaticity is one of the most widely applied concepts within chemistry. It plays a major role
in the rationalization of a range of chemical properties in the electronic ground state, despite …

1.1. History and Background Knots and links are all around us (Figure 1). Be they functional
or decorative, we encounter them constantly, when, for example, tying simple bow knots in …

Since 1996, a growing number of strained macrocycles, comprising only sp2‐or sp‐
hybridized carbon atoms within the ring, have become synthetically accessible, with the [n] …

Since the beginning of scientific chemistry, chemists have been interested in light as an
energy source to induce chemical reactions. 1 Absorbing light, molecules reach an …

The chemistry of expanded porphyrins, which are higher homologues of porphyrins, has
been intensively explored for the last three decades. Expanded porphyrins exhibit …
