Usage

General Description

7H-Benzo[c]carbazole is a chemical compound that belongs to the class of organic compounds known as carbazoles. Carbazoles are compounds containing a three-ring system consisting of two benzene rings fused with a pyrrole ring. 7H-Benzo[c]carbazole, specifically, is characterized by its planar geometry and aromaticity. It is a polycyclic aromatic hydrocarbon, which means it has multiple interconnected aromatic rings. The compound is often used in organic chemistry as a building block for synthesizing more complex structures, including certain types of dyes and drugs. However, it can also be a health hazard as it is a possible carcinogen.

A design strategy of bipolar host materials for more than 30 times extended lifetime in phosphorescent organic light-emitting diodes using benzocarbazole and quinazoline

Stable host materials based on benzocarbazole and quinazoline were synthesized to establish a design strategy of bipolar hosts for elongated lifetime in orange phosphorescent organic light-emitting diodes (PHOLEDs). Three host materials with benzocarbazole and quinazoline connected directly or through a phenyl linker were compared in terms of the device lifetime of the orange PHOLEDs. The connection between benzocarbazole and quinazoline through a phenyl linker was an effective way of improving the lifetime of the red PHOLEDs by more than twice and the molecular orbital distribution of the hosts was well correlated with the lifetime of the PHOLEDs. In particular, the lifetime of the PHOLEDs was extended by more than 30 times compared to a conventional PHOLED with a common CBP host.

Visible-light-driven Cadogan reaction

Visible-light-driven photochemical Cadogan-type cyclization has been discovered. The organic D-A type photosensitizer 4CzIPN found to be an efficient mediator to transfer energy from photons to the transient intermediate that breaks the barriers of deoxygenation in Cadogan reaction and enables a mild metal-free access to carbazoles and related heterocycles. DFT calculation results indicate mildly endergonic formation of the intermediate complex of nitrobiarenes and PPh3, which corresponds with experimental findings regarding reaction temperature. The robust synthetic capacity of the photoredox Cadogan reaction systems has been demonstrated by the viable productivity of a broad range of carbazoles and related N-heterocycles with good tolerance of various functionalities.
