Ecotoxicology and Environmental Safety, 2023 Recently there are increasing interests in accurately evaluating the health effects of heterocyclic PAHs. However, the activation mechanism and possible metabolites of heterocyclic PAHs catalyzed by human CYP1A1 is still elusive to a great extent.

Acta Crystallographica Section E Structure Reports Online, 2012 The title compound, C(14)H(9)N, is the second crystallographically characterized example of an ynamine with an H atom in the C-terminal position. There are two independent mol-ecules (A and B) in the asymmetric unit. The structures of both mol-ecules are essentially planar (r.m.s. deviation = 0.0312 and 0.0152 Å). The N-C(sp) bond lengths are 1.353 (4)

Acta Crystallographica Section E Structure Reports Online, 2013 In the title molecule, C12H8N2O2, the nitro group is tilted slightly with respect to the carbazole moiety [angle between the least-squares planes = 4.43 (9)°]. In the crystal, the molecules are connected via pairs of N—H...O hydrogen bonds into dimers with -1 symmetry. The dimers in turn are arranged into layers parallel to (10-1).

Advanced Functional Materials, EarlyView.Aggregates of diketopyrrolopyrrole dipolar and quadrupolar systems exhibit panchromatic absorption spectra extending in the entire visible range. Upon aggregation in water and in the solid state, their fluorescence is almost completely quenched and their singlet excited state lifetime is significantly shortened.

The Effect of Purcell Cavities on the Lifetime of Thermally Activated Delayed Fluorescent Emitters
Advanced Functional Materials, EarlyView.A pressing challenge to OLED displays and lighting is to balance high efficiency and long operational lifetime in the deep blue spectrum. The Purcell effect can reduce the triplet density and hence the probability for destructive energy‐driven triplet annihilation events that limit the OLED lifetime. Here we study of the Purcell effect on two different
