Abstract:
1. A method for forming a film having electro-optic activity, comprising: (a) depositing a crosslinkable compound onto a substrate to provide a film, wherein the crosslinkable compound has the formula: wherein D is a π-electron donor group, π B is a bridge group, π A is a π-electron acceptor group, wherein D is electronically conjugated to A through B optionally through π-bridges π D D wherein the one or more crosslinkable groups are reactive toward Diels-Alder (4+2) cycloaddition, wherein the crosslinkable groups are independently selected from the group consisting of anthracenyl groups and acrylate groups, n is 0, 1, or 2, m is 0, 1, or 2, and m+n is ≧1; (b) applying an aligning force to the film at a temperature sufficient to provide a film having at least a portion of the compounds aligned; (c) heating the film having at least a portion of the compounds aligned at a temperature sufficient to effect compound crosslinking; and (d) reducing the temperature of the film to provide a hardened film having electro-optic activity.
