Langmuir films of dichroic dyes with fluorescent properties

Spectral properties of some fluorescent dyes in two-dimensional films formed by means of Langmuir–Blodgett technique

“…As it was discussed in detail in Ref. [11] it depends strongly on the molecular structure of the side groups attached to the main skeleton of the molecule. We have also recorded peA isotherms for Langmuir films of dyes 1e4 mixed with AA and 8CB.…”

Spectral and orientational properties of new group of naphthalene derivatives of bicarboxylic acid in liquid crystal 7CB

“…These features cause that these dyes are very attractive for their potential application in passive and active guest-host liquid crystal displays [4]. Recently, it was found that some of naphthalene derivatives of bicarboxylic acid are able to form stable and compressible Langmuir films, which can be easy transferred onto solid substrates making LangmuirBlodgett films [5][6][7][8]. This gives the possibility to use these dyes as active layers in organic light emitting diodes [9].…”
