Paragraph 0096; 0097; 0100, (2018/04/28)
The invention provides a naphthyridine-substituted anthracene derivative, having a structure shown as in general formula (I) that is shown in the description, wherein L is selected from a chemical bond, a substituted or non-substituted C6-12 arylene or sub-polycyclic-aromatic group, and substituted or non-substituted C3-12 sub-heteroaryl or sub-condensed-heterocyclic-aromatic group, Ar1 and Ar2 are separately and independently selected from a substituted or non-substituted C6-30 aryl or polycyclic aromatic group and a substituted or non-substituted C3-30 heteroaryl or condensed-heterocyclic-aromatic group, and R1, R2, R3 and R4 are separately and independently selected from hydrogen, C1-10 alkyl, halogen, cyan, nitro, substituted or non-substituted C6-30 aryl or polycyclic aromatic group,and substituted or non-substituted C3-30 heteroaryl or condensed-heterocyclic-aromatic group. The naphthyridine-substituted anthracene derivative has high electron migration rate and good stability and assists in evaporation film-forming when applied to organic light emission.

Realization of efficient deep-blue anthracene-based emitters with superior film-forming and charge transport properties is challenging. A series of non-symmetric 9,10-diphenylanthracenes (DPA) with phenyl and pentyl moieties at the 2nd position and alkyl groups at para positions of the 9,10-phenyls were synthesized and investigated. The non-symmetric substitution at the 2nd position enabled to improve film forming properties as compared to those of the unsubstituted DPA and resulted in glass transition temperatures of up to 92 °C. Small-sized and poorly conjugated substituents allowed to preserve emission in the deep blue range (-3-1 × 10 -2 cm2 V-1 s-1) in the solution-processed amorphous films of the DPA compounds.

The steric effect of peripheral functional groups on the [4+4]-photocycloaddition between substituted anthracene derivatives was examined. The reactivity of 2,3,6,7-tetraphenylanthracene (TPA) with 2-phenylanthracene (PA), 2,9,10-trimethylanthracene (TMA) and 9,10-dimethyl-2,3-diphenylanthracene (DMDPA) was investigated. In all cases, the photodimers were formed in high yield despite the steric bulk of the peripheral substituents. It was further shown that although PA is capable of forming its homodimer, it selectively reacts with TPA when the latter is excited at 301 nm.
