A major objective of this research program has been to explore unique optical effects which we have speculated to exist in ladder polymers. By steadily improving the solubility and processability through utilization of derivitization and precursor routes we have been able to form the first optical quality films of a ladder polymer and have achieved high resolution characterization of optical nonlinearity in these materials. We have thus succeeded in all our stated objectives, in addition we have examined for the first time numerous other systems of promising optical nonlinearity. Details of the synthesis, characterization and optical measurements of the most promising of the systems examined is contained in the body of this report. At the moment it is sufficient to say that an enormous amount of original research has been achieved through direct support of this grant, a measure of this can be readily seen if one examines the accompanying bibliography of manuscripts published through AFOSR support.
