Provided are compounds having molecular components capable of transporting/injecting hole and an organic EL device having a self-assembled monolayer comprising the same. The compound has the following formula:
Ar—R—SiX
3
wherein Ar is a functional group having hole transporting or injecting capability, R is a C
1
to C
22
alkyl group, and X is an alkoxy group or halogen.
The present invention provides hyperpolarizable organic chromophores. The chromophores are nonlinear optically active compounds that include a &pgr;-donor conjugated to a &pgr;-acceptor through a &pgr;-electron conjugated bridge. Macromolecular structures including the hyperpolarizable organic chromophores are also provided.
AbstractOrganometallic half‐sandwich IrIII complexes of the type [(η5‐Cpx)Ir(N^N)Cl]PF6 (Cpx: Cp* or its phenyl Cpxph or biphenyl Cpxbiph derivatives; N^N: triphenylamine (TPA)‐substituted bipyridyl ligand groups) were synthesized and characterized. The complexes showed excellent bovine serum albumin (BSA) and DNA binding properties and were able to oxidize NADH to NAD+ (NAD=nicotinamide adenine dinucleotide) efficiently. The complexes induced apoptosis effectively and led to the emergence of reactive oxygen species (ROS) in cells. All complexes showed potent cytotoxicity with IC50 values ranging from 1.5 to 7.1 μm toward A549 human lung cancer cells after 24 hours of drug exposure, which is up to 14 times more potent than cisplatin under the same conditions.
