摘要:
Novel biphenyl and biphenyl-like cannabinoid compounds are presented. These compounds, when administered in a therapeutically effective amount to an individual or animal, result in a sufficiently high level of that compound in the individual or animal to cause a physiological response. The physiological response useful to treat a number of physiological conditions.
摘要:
The present invention is directed to a photoactive device comprising an anode, a cathode, and a photoactive layer, which device further comprises an electron transport and/or anti-quenching layer which minimizes both electron transfer quenching and energy transfer quenching of the photoactive layer.
摘要:
The present invention relates to polymeric charge transport compositions. The invention further relates to electronic devices in which there is at least one active layer comprising such charge transport compositions.
摘要:
The disclosure is of a process for recovering valuable by-products of the condensation of phenol and a ketone from a mother liquor obtained for example upon crystallization of a 1:1 adduct of phenol and bisphenol, said mother liquor containing phenol, bisphenol, isomers, contaminant by-products of the condensation reaction of phenol with the ketone and acidic impurities. The mother liquor is distilled/evaporated leaving a tarry residue, which is the feedstock for the process of the invention. The recovery comprises heating the feedstock with proportions of an arylamine salt, to extract the bisphenol-A values as aminophenylhydroxylphenyl-alkanes.
摘要:
A compound of formula (I), where x is 3, 2 or 1, y is 0 or 1, n 1 and n 2 , which may be the same or different, are 0 or 1 to 3, X represents a divalent mono- or poly-aromatic and/or heteroaromatic moiety, the or each Y, which may be the same or different if x is 1, represents hydrogen or an optionally substituted hydrocarbon group, Z represents an aromatic group, or an inherently at least partly conjugated dendritic molecular structure comprising one or more aromatic and/or heteroaromatic groups and, optionally, alkenylene groups, connected to each other either directly or via a carbon atom of an alkenylene group, if present, to a ring carbon atom of an (hetero) aromatic group to which more than one at least partly conjugated dendritic chain is attached, said molecular structure being connected to the remainder of the molecule via a ring carbon atom, one or more of the (hetero) aromatic rings of the dendrimers optionally being substituted, Z and/or the remainder of the molecule, excluding any groups Y, being luminescent, with the proviso that when Z represents an aromatic group y must be 1.
