Langmuir blodgett films

Claim 1

A Langmuir-Blodgett (LB) film of ABAB structure composed of a combination of compounds A and B which are different and which are selected from the group consisting of: AB combinations wherein A has the formula E-C-F and B has the formula E 1 -C 1 -F 1 , wherein E and E 1 are independently CH 3 (CH 2 ) i --where i is 2-20, F and F 1 are independently --(CH 2 ) j --COZ wherein j is 1-10 and Z is --OH, C 1-6 alkyl or NR 1 R 2 wherein R 1 and R 2 are independently H or C 1-6 alkyl, C and C 1 are independently ##STR18## where X and Y are each independently selected from the group consisting of ═NH, ═NR 3 , ═CO, ═CH.CN, ═CHONO, ═CH(Halogen), --COO--, --OOC--, ═CH(ONO)-- CO--NH--, --CO.NR 4 and --O-- where R 3 is C 1-4 alkyl and R 4 is C 1-6 alkyl; AB combinations wherein A is a long chain alkyl amine having the structure C n H 2n+1 ) --NH 2 where n is 16-26, and B is a long chain fatty acid having the structure R 5 (CH 2 ) m COOH where R 5 is selected from the group consisting of CH 3 and CH 2 ═CH and where m is 16-26; AB combinations wherein A is a long chain alkyl amine having the structure C n H.sub.(2n+1) --NH 2 where n is 16-26 and B is a compound of general structure: ##STR19## in which K is 2-20, 1 is 0 to 10, and X, Y and Z are as defined above; and AB combinations wherein A is a long chain carboxylic acid of the formula R 5 (CH 2 ) m COOH where R 5 and m are as defined above and B is a compound of the formula: ##STR20## where K, is 2-20 l, X, Y and Z are as defined above.
