Seven alkylene aromatic polyimides have been synthesised. FT-IR spectra for the polyimides show small regular changes. This shows that the bulk structure of these polyimides changes in a regular fashion, while SEM pictures do not reveal any differenc

Liquid crystal cells with five different polyimide alignment layers have been made for the study of liquid crystals alignment mechanisms. Two of the alignment layers are crystalline and three are amorphous. These cells have been filled with twenty di

The pretilt angle in the nematic phase is related to two different surface dependent factors, while the quality of surface stabilized ferroelectric liquid crystal (SSFLC) devices is dependent on only one of them. We have synthesized two series of pol

Measurements of tilt bias angles of a nematic liquid crystal were carried out, by using several alkylene polyimides synthesized from 3,3′,4,4′-biphenyltetracarboxylic dianhydrides and diamines with different chain lengths as alignment layers. The

Six series of copolyimides have been synthesized. The pre-tilt angle has been measured as a function of the composition of these copolyimides. A linear relationship was found between the pre-tilt angle and the composition when both the simple polyimi

— Existing experimental evidence, such as scanning tunneling microscopy (STM) or second-harmonic generation (SHG), shows that the liquid-crystal molecules are strongly fixed at the polymer surface. The nematic phase in the bulk is uniaxial, which s

Two polyimides have been cured at different temperatures and some samples further annealed at different temperatures after rubbing. It is found that the pretilt angles on these films increase with increasing curing temperature and/or increasing curin

The basic characteristics of new naphthalocyanine derivatives used as a recording layer for a write-once optical storage medium were studied. Read-out stability could be improved by mixing two types of naphthalocyanines: one had a bulky structure wit
