  A complex (10) includes a liquid crystal component (13) and a support (11, 12) of the liquid crystal component (13), in which a lubricating interface derivation region (16) is formed between the liquid crystal component (13) and the support (11, 12). An optical element includes a pair of substrates (11, 12) having electrodes (18, 19) on at least one substrate (11), and a liquid crystal component (13) with which a space between the pair of substrates (11, 12) is filled, in which a lubricating interface derivation region (16) is formed between the pair of substrates (11, 12) and the liquid crystal component (13). It is preferable that the lubricating interface deriving agent (14) is present in the lubricating interface derivation region.

• Branching of the Perfluorinated Chain Influences the Liquid-Crystalline Properties of Semifluorinated Alkanes: Perfluorooctyl- and Perfluoroisononyl-n-Alkanes—a Comparative Study

  Two series of semifluorinated-n-alkanes (SFAs) of comparable perfluorinated chain length but, different terminal group constitution, namely perfluoroctyl-n-alkanes [F-(CF2)(8)-(CH2)(n)-H, in, short F8Hn] and perfluoroisononyl-n-alkanes [(CF3)(2)CF(CF2)(6)-(CH2)(n)-H, in short iF9Hn] were synthesized. Their thermal properties were analyzed by means of differential scanning calorimetry (DSC), on both heating and cooling of the samples. The textures of the synthesized semi-fluorinated alkanes were investigated with the microscopy in polarized light. Similar to previously investigated perfluorodecyl-n-alkanes, perfluorooctyl-n-alkanes containing fewer than 12 methylene groups form smectic B phase. F8H8, F8H9, and F8H10 show a tendency to supercool and preserve smectic B ordering even below the transition temperature. For F8H11, the phase transition front smectic B to 3D crystal structure, manifesting itself as a rapid recrystallization., has been. observed. Perfluorooetyl-n-alkanes of 12 or more methylene groups do not form liquid-crystalline phases. In contrast to perfluorooctyl-n-alkanes, perfluoroisononyl-n-alkanes are not capable of liquid-crystalline phase formation, regardless of the hydrogenated moiety length and the experimental conditions.
