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 …

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 …

Photomechanical crystals are interesting from both basic and applied perspectives, and thus
it is important to develop new examples. We investigated the photomechanical bending …

Upon exposure to UV light, the disubstituted dibenzobarrelene derivative 1a turns green in
the solid phase and reverts back to its original pale-yellow color within several hours in the …

We could access for the first time a 5-phosphasemibullvalene derivative via quantitative and
selective photochemical di-π-methane rearrangement from the corresponding …

The di‐π‐methane (DPM) rearrangement reaction is one of the most studied photochemical
transformations. The oxa‐di‐π‐methane (ODPM) rearrangement reaction has been …

It is demonstrated that the di‐π‐methane (DPM) rearrangement of carbonyl‐substituted
dibenzobarrelene (9, 10‐dihydro‐9, 10‐ethenoanthracene) derivatives is induced by visible …

Chemoselective photorearrangements of symmetrically substituted pyrazinobarrelene 4,
quinoxalinobarrelene 5, and benzoquinoxalinobarrelenes 6 and 7 containing polar and non …

Chemoselective photorearrangements of pyrazino-, quinoxalino-, and
benzoquinoxalinobarrelenes were investigated by deuterium-labeling experiment …

This chapter aims to cover important developments on the photophysical and photochemical
properties of transition-metal complexes for the period between June 2004 and July 2007 …
