Usage

Uses

2-BroMo-5,7-dihydro-7,7-diMethyl-5-phenyl-indeno[2,1-b]carbazole can be used as organic synthesis intermediate and pharmaceutical intermediate, mainly used in laboratory research and development process and chemical industry during production process.

Synthesis

The resulting 12,12-dimethyl-10-phenyl-10,12-dihydroindeno[2,1-b]carbazole (7.5 g) and DMF (53 ml) were added to a reaction vessel. N-bromosuccinimide (3.72 g) was added under ice-cooled conditions, and the mixture was stirred for 9 hours and then left for one night. Water (260 ml) was added, and the mixture was subjected to filtration to obtain a brownish white powder of 7-bromo-12,12-dimethyl-10-phenyl-10,12-dihydroindeno[2,1-b]carbazole (8.67 g; yield 94.6%).

The present invention provides a photoelectric conversion device comprising an organic thin film containing a compound having an indenocarbazole ring structure represented by the following general formula (1). (In the formula, A represents a single bond, a divalent substituted or unsubstituted aromatic hydrocarbon group, etc.; Ar1, Ar2 and Ar3 each represent a substituted or unsubstituted aromatic hydrocarbon group etc.; R1 to R9 each represent a hydrogen atom or an optionally substituted linear or branched alkyl group having 1-6 carbon atoms; and R10 and R11 each represent an optionally substituted linear or branched alkyl group having 1-6 carbon atoms, a substituted or unsubstituted aromatic hydrocarbon group, etc.).

Compound with carbazole as core, and application thereof in organic light-emitting devices

The invention relates to a compound with carbazole as a core, and a preparation method and an application thereof. The structure of the compound is characterized in that carbazole is connected with atriphenylamine structure through a carbon-nitrogen bond, and the carbon-nitrogen bond connection avoids exposure of an active position; carbazole is connected with a dibenzo five-membered ring througha carbon-carbon bond, so the chemical stability of the above material is improved; the whole molecule is of a large rigid structure, and has a high triplet state energy level (T1); the compound has alarge steric hindrance, and is not prone to rotate, and the three-dimensional space structure is stable, so the compound has a high glass transition temperature and a high molecular thermal stability; and HOMO and LUMO distribution positions of the compound are separated from each other, so the compound has appropriate HOMO and LUMO energy levels, thereby the compound can effectively improve theluminous efficiency and the service life of OLEDs when applied to the OLEDs.

Highly efficient non-doped deep-blue organic light-emitting diodes by employing a highly rigid skeleton

Two novel deep-blue emitters based on a highly rigid unit, IDC-PA and IDC-Py, were prepared by respectively introducing the 7,7-dimethyl-5-phenyl-5,7-dihydro indeno [2,1-b] carbazole (IDC) unit with anthracene and pyrene derivatives. The emitters exhibit
