Organic luminous compound and preparation method thereof, and organic electroluminescent device

The invention provides an organic luminous compound with a structure as shown in a formula (I) which is described in the specification. According to the invention, a benzimidazole compound is introduced into the mother nucleus of anthracene, and the positions and amount of linking groups are changed so as to improve the electron mobility of the luminous compound; and when used as an electron transport layer material for an organic electroluminescent device, the luminous compound has substantially improved luminous efficiency and life compared with other electron transport layer materials. Theorganic luminous compound uses easily available raw materials and is short in synthesis route, simple in process, low in cost and suitable for industrial production.

Impact of non-symmetric 2,9,10-aryl substitution on charge transport and optical properties of anthracene derivatives

A new methodology for the synthesis of non-symmetric 2,9,10-arylanthracenes is proposed. The anthracenes were intentionally decorated with non-symmetric aryls to improve charge transport properties. The impact of non-symmetric aryl substituents on optical and electrical properties was thoroughly studied. Non-symmetric 9,10-aryl substituents ensured blue emission in the range of 422-436 nm and fluorescence quantum efficiency of ca. 0.45, while the type of substituents had a minor impact on excited state deactivation due to their twisted configuration. Optical properties of the compounds obtained in dilute solution and in a rigid polymer matrix revealed the dominating non-radiative decay mechanism to be due to the intersystem crossing (ISC), which was mainly governed by 2-phenyl substitution. Favourable alignment of the singlet and triplet energy levels for efficient ISC was confirmed by density functional theory calculations. Some of the non-symmetrically substituted anthracene derivatives showed very high hole drift mobilities reaching 10-2 cm2/Vs in solution-processed neat films.
