Color filter, method for manufacture thereof and liquid crystal

A process for producing an organic thin film comprising solubilizing a hydrophobic organic substance with a surfactant containing a ferrocene compound in an aqueous medium to form a micelle solution, and electrolyzing the micelle solution to form a thin film of the hydrophobic organic substance on an electrode. The ferrocene compound has the formula: ##STR1## G is hydrogen, methyl or ethyl, R.sup.4 is hydrogen, methyl or ethyl,

Process for producing organic thin films

Process for producing ferrocenoyl derivatives

Ferrocene compounds represented by the formula: ##STR1## wherein A indicates ##STR2## wherein X is --CH.sub.2 --, --O--, ##STR3## G is a hydrogen atom, a methyl group, or an ethyl group, R.sup.4 is a hydrogen atom, a methyl group or an ethyl group, and m is a positive integer satisfying the expression 0.ltoreq.k+m.ltoreq.10, Z is --O-- or ##STR4## and R.sup.1 and R.sup.2 are identical or different and each is H, NH.sub.2, N(CH.sub.3).sub.2, CH.sub.3, CH.sub.3 O, OH or a halogen atom, and R.sup.3 is a hydrogen atom or a methyl group, k is a positive integer satisfying the expression 0.ltoreq.k+m.ltoreq.10, and n is a real number of 2 to 70, a is an integer of 1 to 4, and b is an integer of 1 to 5. Also provided by the invention are surfactants containing said ferrocene compounds. Further provided is a process which comprises making hydrophobic organic substances soluble in an aqueous medium with the use of a surfactant containing the ferrocene compound described above, and electrolyzing the micelle solution thus obtained to form a thin film of the aforementioned hydrophobic organic substance on the electrode. The ferrocene compounds can be used in various applications including surfactants (micelle forming agents), catalysts, auxiliary fuels, flotating agents, lubricating aides, dispersants, liquid crystals and the like.
