  Regioselectivity control of photodimerization of liquid-crystalline cinnamoyl compounds by phase variation: dual functionality of p-terphenyl substituent as a mesogen and a triplet sensitizer

  摘要：

  Cinnamoyl-functionalized liquid-crystalline (LC) compounds having a 4 ''-substituted [1,1';4',1 '']terphenyl (p-terphenyl) as mesogens were synthesized to investigate the abilities of the mesogen to act as a triplet sensitizer. UV (365 nm) irradiation of the LC compound having 4 ''-cyano-p-terphenyl in the crystalline and LC phases regioselectively produced the photodimers with a head-to-tail and a head-to-head cyclobutane unit, respectively. The p-terphenyl thus played the role of triplet sensitizer because the cinnamoyl group does not absorb 365 nm light. Due to the dual functionality of the p-terphenyl as the mesogen and the triplet sensitizer, we successfully performed the photochemical and regioselective cycloaddition to obtain two different LC dimers from one LC monomer.

  The use of a mesogenic compound having a terminal end chain comprising carbon, oxygen, or sulphur, which has at least one pendent C 1-4 alkyl, C 1-4 alkoxy or a cycloalkyl ring, arranged no more than 6 atoms from the end of the chain either decreasing the melting point, increasing the clearing point, increasing the speed of switching and/or increasing the tilt angle of a liquid crystal mixture. Examples of such compounds are of formula (I) where M is a mesogenic core group, and X and Y are terminal groups, provided that at least one group X or Y is a group of sub-formula (i) where Z 1 , Z 2 , R 1 , R 2 , R 3 , R 4 , R 5 , R 6 , R 7 , s, q, m and n are as defined in the specification. Novel compounds of formula (I) are also described and claimed. 1
