Makarov,Maksimova,Baranov,Fukin,Suvorova,Woehrle,Domrachev
, p. 1748 - 1754 (2006)
Dimeric phthalocyanines of a new type with a bridging 9,9,10,10- tetramethyl-9,10-dihydroanthracene fragment were synthesized. On the basis of X-ray diffraction analysis and molecular modeling of 9,9,10,10-tetramethyl-9,10- dihydroanthracene, a nearly pla
Metal-ammonia reduction-V. The stereochemistry of reductive alkylation
Harvey,Arzadon
, p. 4887 - 4894 (1969)
Reductive alkylation of anthracene, 9, 10-dimethylanthracene, 1, 4-dimethylanthracene, benz(a)anthracene and dibenz(a,h)anthracene via treatment of the dilithio adducts in liquid ammonia with alkyl halides proceeds stereo selectively to furnish high yields of the corresponding cis-dialkyldihydro derviatives.

, (2009/04/24)
The invention provides a host material for organic light emitting diodes, having the general formula: wherein R1 is selected from a C1-8 alkyl group, each R2 is independently selected from a hydrogen or a C1-8 alkyl group, Ar is selected from a C5-14 aromatic or hetero aromatic group, R3 is selected from a C5-14 aromatic or hetero aromatic group, a C1-8 alkyl group, a C5-8 cycloalkyl group, a C1-8 fluoroalkyl group, or a C1-8 alkoxyl group, and n is an integer of 1-10. The host materials have a higher energy gap (greater than 4.0 eV), and high thermal stability.
