Abstract:
A polarized film, comprising: at least one molecular bilayer having the formula: ##STR13## wherein: n is the number of bilayers, is from 1 to 4000;F is a semi-ionic mainchain, head-to-head chromophoric polymer which is represented by the formula: ##STR14## which floats on a liquid subphase of a Langmuir-Blodgett trough and is essentially insoluble in said subphase during the film deposition process;S is an ionic molecule having essentially no nonlinear optical properties and having the opposite charge of F, and said S is soluble in said subphase;B.sub.NFD is a nonionic bridging group, extending between and being part of said electron donating ends of two C.sub.F chromophores;B.sub.IFA is an ionic bridging group, extending between and being part of said electron accepting ends of two C.sub.F chromophores;C.sub.F chromophores have an electron accepting group at one end (nearest B.sub.IFA), and an electron donating group at the other end (nearest B.sub.NFD), and a rigid group which contains delocalized p-electrons electronically connecting the electron accepting end and the electron donating end of said chromophores;y.sub.F is the degree of polymerization of F, which ranges from a minimum value of 2 to a maximum value of about 300.
