Abstract:
1. A film forming, photoactive, homogeneously mixed material comprising an ionic complex prepared from (a) at least one ionic photosensitive compound which may undergo a photoreaction, selected from photoisomerizations, photocycloadditions and photoinduced rearrangements, wherein the photosensitive compound is of formula I or formula II  wherein P is a group capable of photoisomerization, and R and R′ are independently selected from optionally substituted or functionalized aryl-containing groups at least one of which is positively or negatively charged, A is an oppositely charged cation or anion, n is an integer, and x is 1, 2 or 3, and/or the photosensitive compound is of formula III or IV:  wherein Q is a group capable of participating in a photocycloaddition or photoinduced rearrangement reaction, and R with the proviso that in all compounds of formulae (I) to (IV) contained in one complex, the charge of [R—P—R′] and/or [R and/or (a′) at least one photosensitive polyelectrolyte (“second polyelectrolyte”) carrying residues which may undergo a photoreaction, selected from photoisomerizations, photocycloadditions and photoinduced rearrangements, wherein said second polyelectrolyte essentially consists of or mainly comprises at least one structure according to formula Ia or formula IIa and/or of formula IIIa or IVa: wherein Pol means a repeating unit of a linear or branched polymer chain, o indicates the number of the repeating unit of the polymer chain, and (R*—P—R′) and (R P, R′, R wherein at least one of R* and R′ is positively or negatively charged, R o is at least 2, preferably between 2 and 1,000, but can be even higher, with the proviso that in one complex, groups [R*—P—R′] and/or [R and (b) at least one polyelectrolyte carrying charges which are opposite to those of the active groups [R—P—R′] and/or [R
