摘要：

The pH effect on arrangement of a liquid crystal (LC) system was studied in short and rigid molecule (BDMT-Hg). 1,4-benzenedimethanethiol (BDMT) doped 4-cyano-4'-currency-pentylbi-phenyl (5CB) was spontaneously generated on n-octyltrichlorosilane (OTS)-treated glass. A homeotropic alignment of an LC system of BDMT-LC was observed under polarized optical microscope (POM) when using BDMT as low as 6% (w/v). A short and rigid BDMT-Hg complex was formed in liquid crystal system (BDMT-Hg/LC system) at pH 7-8 and exhibits crosspolarized images in 48 hours.
