A based on the four phenyl silicon substituted alkoxyl benzoin and thiophene derivatives, process for preparation thereof (by machine translation)

The invention discloses a based on four phenyl silicon substituted alkoxyl benzoin and thiophene derivatives, the derivatives have the structure shown below: , The invention is based on four phenyl silicon substituted alkoxyl benzoin and thiophene derivatives are OLED hole transporting material in the device, with four phenyl silicon as the main body, is connected with the with a hole on the location of transmission capacity dibenzo thiophene, in order to better adjust energy HOMO, in dibenzothiophenes is introduced to the electronic capacity with alkoxy, HOMO energy level of the material for improving, enhancing its glass transition temperature, the triplet energy level has higher, and has excellent hole-transporting ability. The preparation process of the invention is simple, as the OLED display and illumination provides excellent material. (by machine translation)

Organic charge transporting material and preparation method therefor

The invention discloses an organic charge transporting material which has a structure represented by a formula shown in the description. The organic charge transporting material disclosed by the invention is a hole-transporting material in an OLED apparatus. By using tetraphenyl-silicon as a main body, dibenzothienyl groups with hole-transporting ability are connected to para-positions of tetraphenyl-silicon. In order to better adjust the HOMO energy level, butoxy goups with electron donating ability are introduced onto the dibenzothienyl groups, so that the HOMO energy level of the material is improved, the glass transition temperature of the material is improved, and the material has a relatively high energy level in a triplet state and has excellent hole-transporting ability. The material disclosed by the invention is simple in preparation process and provides an excellent material for OLED display and illumination.
