2,3,4,9-Tetrahydro-1H-carbazole [PDF]
Acta Crystallographica Section E Structure Reports Online, 2008 In the title compound, C(12)H(13)N, two methyl-ene C atoms of the cyclo-hexene ring are disordered over two sites with occupancies of 0.591 (10) and 0.409 (10); both disorder components adopt half-chair conformations. The crystal structure is stabilized by inter-molecular N-H⋯π and C-H⋯π inter-actions.

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

1-[6-(9H-Carbazol-9-yl)hexyl]-2-phenyl-1H-benzimidazole
Acta Crystallographica Section E, 2009 The molecule of the title compound, C31H29N3, contains a hexyl chain, a coordination unit (benzimidazole) and a functional group (carbazole). The benzimidazole ring is not coplanar with either the phenyl ring or the carbazole system, making dihedral ...

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)

Charge Transport in Ternary Charge‐Transfer Solid Solution Single Crystals
Advanced Functional Materials, EarlyView.This study deconvolutes the roles of indirect (superexchange) and direct electronic coupling on charge transport in single crystals of an organic charge‐transfer molecular semiconductor (OSC). This model system elegantly demonstrates that structural defects introduced by chemical dopants play a significant role in the electronic performance ...
