Functionalized Photoreactive Compounds

The present invention concerns functionalized photoreactive compounds of formula (I), that are particularly useful in materials for the alignment of liquid crystals. Due to the adjunction of an electron withdrawing group to specific molecular systems bearing an unsaturation directly attached to two unsaturated ring systems, exceptionally high photosensitivities, excellent alignment properties as well as good mechanical robustness could be achieved in materials comprising said functionalized photoreactive compounds of the invention.

PROCESS FOR THE PRODUCTION OF ETHER ISOCYANATES BACKGROUND OF THE INVENTION

Ether isocyanates are prepared by phosgenation of ether amines in the vapor phase.

Macrocyclic oxamides

Macrocyclic oxamides may be made easily, in good yield and in one step by reacting an oxalic compound, such as oxalic acid or oxalic esters, with a diamine, where the amine groups are separated by at least five atoms. The oxalic compounds may include, but are not limited to such materials as dimethyl oxalate and diethyl oxalate. The diamines may include, but are not limited to such materials as alkylenediamines; polyalkylene glycol diamines; alkyl-bis-(aminoalkyl)amines; imino bis-(alkyl)amines; and N,N' bis-(aminoalkyl)-N,N'-dialkylalkylenediamines and bis-(aminoalkyl)piperazines; and mixtures thereof. The macrocyclic oxamides made by this process may be used to selectively separate metal ions from solution, or complexed together with a metal ion act as a catalyst.

Precursor to nucleic acid probe

Nucleic acids may be labeled by intercalating the alkylating intercalation moiety of a labeling reagent into a partially double-stranded nucleic acid to form a complex and activating the complex to cause covalent bonding between the reagent and the nucleic acid. Preferably, the labeled nucleic acid is a hybridization probe for detecting nucleic acid sequences capable of hybridizing with a hybridizing region of the nucleic acid. Also preferably the label moiety is non-radioactive. The labeling reagent is of the formula: where A is an alkylating intercalation moiety, B is a divalent organic moiety of the formula: STR1 where Y is O, NH or N--CHO, x is a number from 1 to 4, y is a number from 2 to 4, and L is a monovalent label moiety, wherein B is exclusive of any portion of the intercalation and label moieties. Preferably A is a 4-methylene-substituted psoralen moiety, and most preferably A is a 4'-methylene-substituted-4,5', 8-trimethylpsoralen moiety and L is biotin.
