Gain of aromaticity or relief of antiaromaticity along a reaction path are important factors to
consider in mechanism studies. Analysis of such changes along potential energy surfaces …

Long-wavelength, near-infrared small-molecule dyes are attractive in biophotonics.
Conventionally, they rely on expanded aromatic structures for redshift, which comes at the …

Organic chromophores with large Stokes shifts and dual emissions are fascinating because
of their fundamental and applied interest. Vibration-induced emission (VIE) refers to a …

Herein we describe the anion of benzo [b] phenothiazine as a super reductant species upon
excitation by visible light. In contrary to N-substituted phenothiazines or …

It is commonly accepted that a large π-conjugated system is necessary to realize low-energy
electronic transitions. Contrary to this prevailing notion, we present a new class of light …

We demonstrate that a single polycyclic π‐scaffold can undergo sequential multistep excited‐
state structural evolution along the bent, planar, and twisted conformers, which coexist to …

Singlet exciton fission photovoltaic technology requires chromophores with their lowest
excited states arranged so that 2 E (T1)< E (S1) and E (S1)< E (T2). Herein, qualitative …

To gain insights into the coupling of conformational and electronic variables, we exploited
steric hindrance to modulate a polycyclic skeleton with a bent conformation in the S0 state …

We here disclose that the incorporation of thiophene rings into a seven‐membered 8π
azepine in a fused fashion produces a useful antiaromatic core for near‐infrared (NIR) dyes …

Excited-state aromatization dynamics in the photochemical ring opening of dihydroazulene
(DHA) is investigated by nonadiabatic molecular dynamics simulations in connection with …
