Multiple hydrogen bonded mesomorphic complexes between complementary 1,3,5-triazine and pyrimidine derivatives

A 2,4-diamino-6-phenyl-1,3,5-triazine grafted with two semiperfluorinated chains at the phenyl substituent has been investigated in binary mixtures with complementary orotic acid and barbituric acid derivatives carrying either a lipophilic alkyl or a semiperfluoroalkyl tail. Equimolar mixtures of the triazine with nucleobases form triple hydrogen-bonded heterodimers with an elongated central core. Mesomorphic properties are observed only if the pyrimidinone component provides an additional free NH function not involved in triple H-bonding with the triazine nucleus. In that case, additional H-bond interactions orthogonal to the rod-shaped core of the heterodimers initiate the formation of cyclotrimeric rosette-type associates with circular geometry of the polar core region. Rosettes of heterodimers involving an alkyl substituted nucleobase organize to hexagonal columnar mesophases. Replacing the alkyl tail of the pyrimidine with a semiperfluorinated fragment leads to the formation of a micellar cubic phase. The individual micelles are composed of segmented columns three-dimensionally surrounded by a continuum of the semiperfluorinated segments.

PREPARATIONS CONTAINING AMINO ACIDS AND OROTIC ACID

The present invention describes compounds produced from an orotic acid molecule and an amino acid molecule. The compounds being in the form of amino acid orotate compounds bound by an amide linkage and produced by one of two disclosed methods; 1) reacting orotic acid or derivatives thereof with a thionyl halide, and then combining the acyl halide with an amino acid in the presence of dichloromethane and a DMAP catalyst; or 2) protecting the carboxylic acid of an amino acid and then combining the amino acid with a DCC activated orotic acid, followed by removal of the carboxylic acid protecting group. The resulting amino acid orotate amide has an enhanced stability in solution as compared to a related ester. In addition, specific benefits are conferred by the particular amino acid used to form the compounds in addition to, and separate from, the orotate substituent.
