Photoactive thin film, its preparation and use, the formation of the optically anisotropic structure and surface relief caused by and irradiating the thin film

摘要

The present invention, there is provided a homogeneous photoactive thin film of them alone, or containing a polymer electrolyte having a residue undergoes a photoreaction, the formula (I) ~ ie (IV), the polymer electrolyte, [Pol ( ^{R *} -P-R')] _o^{on + n} / ^xA x- (I), ⁿ / xA ^x + ^[Pol (R ^* -P-R')] _o^on- (II), ^[Pol (R ^{1 *} - from the structure of at least one ^{Q-R 1} ')] _o^{on + n} / ^xA x- (III), ⁿ / xA ^x + ^{[Pol (R 1} * ^{-Q-R 1'} or one of)] _o^on- (IV) on homogeneous photoactive thin film composed of the main. Here, Pol is a repeating unit of the polymer chain branched or linear, to represent the number of repeating units in the polymer ^chain, and (R * -P-R') o is, ^{(R 1} * -Q-R 1 A '), and positively or negatively charged, an n fold side chains of the repeating unit Pol, where, P is a group capable of undergoing a photo-induced E / Z isomerization, Q is photoaddition cyclization a group capable of participating in, or a group capable of participating in photoinduced rearrangement, or a group capable of participating in what is referred to as the light over Fries reaction, A is oppositely charged is an anion or cation has, n is preferably 1 or 2, x is 2 or 1, o is at least 2, except that in the polymer electrolyte of one group and [R-P-R'] / or ^{[R 1} -P-R 1 '] all have the same sign. The present invention further provides a direct its use and how to provide a copy of the thin film of the present invention having the thin film, the surface relief structure.
