  Building Blocks for Oligospiroketal (OSK) Rods and Evaluation of Their Influence on Rod Rigidity

  摘要：

  We report on the synthesis of three new sleeves and their incorporation in OSK rods. The structures of these sleeves are based on neo-inositol, terephthalaldehyde diacetals, and indacene. To quantify the influence of the sleeves on rod rigidity, we applied the worm-like chain (WLC) model on the new rods and found that this approach is rather disappointing. As the chief cause of this result, we assume that the rigidity of typical molecular rods largely exceeds the rigidity of polymers, which were successfully described by the WLC model. Alternatively, we suggest quantifying the rigidity of molecular rods by fitting an empirical function on the end-to-end distance distribution curve obtained by MD simulations. After checking various function types, the Levy-Martin function proved to be most suitable for this purpose. On the basis of this function, we defined the Levy-Martin parameter and suggest using this parameter for the characterization of the rigidity of molecular rods.

  An organic film transistor containing a compound, which is composed of n repeating units represented by Formula (1-1), (1-2), or (101), in a semiconductor active layer is an organic film transistor using a compound that results in high carrier mobility when being used in the semiconductor active layer of the organic film transistor and exhibits high solubility in an organic solvent. (Each of R 1 and R 2 represents a hydrogen atom or a substituent; each of Ar 1 and Ar 2 independently represents a heteroarylene group or an arylene group; V 1 represents a divalent linking group; m represents an integer of 0 to 6; cy represents a naphthalene ring or an anthracene ring; each of R 3 and R 4 represents a hydrogen atom or a substituent; each of Ar 3 and Ar 4 represents a heterocyclic aromatic ring or an aromatic ring; V 2 represents a divalent linking group; p represents an integer of 0 to 6; n represents an integer of equal to or greater than 2; A is a divalent linking group represented by Formula (101′); each of R A1 to R A6 represents a hydrogen atom, a substituent, or a direct bond with Ar 101 or Ar 102 in Formula (101); and among the groups represented by R A1 to R A6 , two different groups are direct bonds with Ar 101 and Ar 102 in Formula (101) respectively.)
