3-(Trimethylsilylethynyl)carbazole

Acta Crystallographica Section E Structure Reports Online, 2003
The title compound, [Si(CH3)3(C14H8N)] is a TMS-protected mono-alkyne. It is used as a model species for platinum σ-acetyl­ide compounds of which it is a precursor. Such compounds are of interest due to the extended π-conjugation through the hetero-aromatic linker unit in the backbone.

Modulating Two‐Photon Absorption in a Pyrene‐Based MOF Series: An In‐Depth Investigation of Structure–Property Relationships

Advanced Functional Materials, EarlyView.
This study investigates H4TBAPy‐based metal–organic frameworks (MOFs) ‐ NU‐1000, NU‐901, SrTBAPy, and BaTBAPy ‐ for multiphoton absorption (MPA) performance. It observes topology‐dependent variations in the 2PA cross‐section, with BaTBAPy exhibiting the highest activity.

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.
