Compound with vertical alignment property, liquid crystal display panel and preparation method of liquid crystal display panel

The invention discloses a compound with vertical alignment property, a liquid crystal display panel and a preparation method of the liquid crystal display panel. In the liquid crystal display panel, aliquid crystal material of a liquid crystal layer is liquid crystal molecules doped with the compound with vertical alignment property; therefore, an alignment layer in the liquid crystal display panel or a polymerizable monomer in a liquid crystal material is omitted, and the liquid crystal display panel has the advantages of simplifying the preparation process, reducing the production cost andimproving the product yield.

Selectivity in the photodimerization of 6-alkylcoumarins

Coumarin and 6-alkylcoumarins (alkyl = C1 to C16) were photodimerized in homogeneous solvents differing in polarity and in aqueous micellar solutions. The four possible photodimers, syn head-to-head (hh), anti head-to-head, syn head-to-tail (ht), and anti head-to-tail, were identified through a combination of X-ray analysis and NMR spectroscopy. In 6-methylcoumarin the concentration-corrected dimerization (quantum) yield increases with decreasing concentration of the educt; anti- hh was formed exclusively in nonpolar solvents and upon triplet sensitization and was the main product under all conditions except for ionic micellar systems, which direct to preferred syn-hh dimerization. Long alkyl substituents, however, lead to anti-hh in polar solvents and in micelles, too. Predominating ht dimer formation was observed for nonsubstituted coumarin in polar solvents only. Thus, syn/anti and hh/ht selectivity can be steered by varying the 6-alkyl substituent. Syn- hh photodimers of 6-methylcoumarin can be photochemically split into the monomers; they partly proved thermally unstable against acids, bases, methanol, and on SiO2 surfaces.
