- A germanium-containing element of the organic electroluminescent material and organic light-emitting device
-
The present invention provides a germanium-containing element of the organic electroluminescent material and organic light-emitting device, which belongs to the technical field of organic photoelectric material. The present invention provides organic electroluminescent material structure containing triphenylgermanium structure in, will enable the compound triplet energy level higher, in addition containing fluorene group also can further improve the triplet energy level, with the energy barrier between the HOMO LOMO greater, more favorable as the blue light emitting material; glass transition temperature is higher, in addition, triphenylgermanium for large non-planar group, fluorene group is the distortion of the rigid radical, can avoid the accumulation of the molecule between the role of the π - π, the compound does not easy to crystallization, avoiding the exciton in the crystallization aggregation quenching. Compared with the prior art, and applied to the organic light-emitting device, especially as used in the luminescent layer, having a relatively high light-emitting efficiency, longer service life.

- Synthesis of benzo[c]fluorenone through a one-pot cascade reaction using inden-1-one derivatives
-
A novel one-pot thermal cycloaddition of two indenones followed by a decarbonylation and dehydrogenation cascade afforded benzo[c]fluorenones regioselectively. Various substituted indenone derivatives were converted into their corresponding benzo[c]fluorenones in good to excellent yields.

- Photobromination of indane: Preparation of bromoindenones and ready access to benzo[c]fluorenone skeleton
-
1,1,3,3-Tetrabromoindane and 1,1,2,3,3-pentabromoindane were efficiently synthesized by photolytic bromination of indane. Subsequent dehydrobromination of them gave the corresponding tribromo- and tetrabromoindenes, which were easily converted to the corresponding bromoindenones by silver-supported hydrolysis. Thermolysis of 3-bromoindenone gave the benzo[c]fluorenone derivative.
