A chemically-responsive bis-acridinium receptor

A dicationic receptor based on two acridinium moieties linked by a triphenylene spacer was studied in solution and in the solid state. Recognition moieties, namely acridiniums, were exploited to evidence a host-guest response of the receptor with electron rich guests. Upon addition of methoxide anions, the formation of the bis-acridane form of the receptor was observed. The chemical responsiveness of the receptor to these anions inhibits its recognition properties towards π-donor guests. In addition, the reversibility of the chemical response was demonstrated under acidic conditions.

ORGANIC ELECTROLUMINESCENT ELEMENT

Disclosed is a highly reliable organic electroluminescent device, in particular, a phosphorescent organic electroluminescent device using a low-molecular-weight host material, wherein a good balance between electron and hole injection and an efficient mechanism of phosphorescence are maintained. The organic electroluminescent device contains a light-emitting layer between an anode layer and a cathode layer and the light-emitting layer comprises a phosphorescent dopant material and a host material with a molecular weight of not more than 10,000. The host material is composed of a first host material and a second host material that is different from the first host material and the first host material differs from the second host material by not more than 0.1 eV in the ionization potential (IP), by not more than 0.1 eV in the electron affinity (EA), and by not more than 0.1 eV in the triplet energy (T1).

NOVEL COMPOUND, MATERIAL FOR ORGANIC ELECTROLUMINESCENCE DEVICE, AND ORGANIC ELECTROLUMINESCENCE DEVICE

A specific material for organic electroluminescence device having m-phenylene skeleton in its molecule realizes a highly heat-resistant and long lifetime organic electroluminescence device capable of driving at low voltage with high efficiency.

COMPOUND FOR ORGANIC ELECTROLUMINESCENT DEVICE AND ORGANIC ELECTROLUMINESCENT DEVICE USING THE SAME

Disclosed is an organic electroluminescent device (organic EL device) that is improved in luminous efficiency, fully secured of driving stability, and of simple structure. The organic EL device comprises a light-emitting layer between an anode and a cathode piled one upon another on a substrate and the light-emitting layer comprises a phosphorescent dopant and a compound containing carbazolyl groups at both ends represented by the following formula (1) as a host material. In formula (1), X is independently CH optionally containing a substituent or N and L is a direct bond, an ethylene group, or an acetylene group.

BISANTHRACENE DERIVATIVE AND ORGANIC ELECTROLUMINESCENT DEVICE USING SAME

Disclosed are bisanthracene derivatives of a specific structure represented by the formula (1) below. Also disclosed is an organic electroluminescent device wherein an organic thin film composed of one or more layers including at least a light-emitting layer is interposed between an anode and a cathode and the organic thin film contains at least one of the bisanthracene derivatives by itself or as a component of a mixture. Such an organic electroluminescent device has long life while exhibiting high luminous efficiency even in the high luminance region. The above-mentioned bisanthracene derivatives enable to realize such an organic electroluminescent device. (In the formula, Ar1 and Ar2 independently represent a substituted or unsubstituted aromatic hydrocarbon group having 6-50 nuclear carbon atoms, Ar3 represents a substituted or unsubstituted phenylene group or the like, R1-R18 independently represent a hydrogen atom or the like, m and n respectively represent an integer of 0-4, q represents an integer of 1-3, and p represents an integer of 0-2.)

SYNTHESES AND PHYSICAL PROPERTIES OF SEVERAL POLYPHENYLENES CONTAINING MIXED LINKAGES.

Fourteen macrocyclic polyphenylenes, including ten new compounds, were synthesized by intra- or intermolecular homo-coupling of di-Grignard compound and by cross-coupling of two kinds of di-Grignard compounds with copper(II) chloride, **1H NMR spectra of the polyphenylenes, compared with those of open-chain analogues, provide valuable information on the nonplanar spacial relationship of constituting phenylene rings. UV spectra of the compounds containing p-phenylene ring(s) suggest that the lack or decrease in intensity of K-band above ca. 260 nm or a marked shift of that band provides useful conformational information. Empirical Hueckel molecular orbital calculations of longest-wavelength absorption bands of twelve polyphenylenes were also carried out.
