Abstract

x(3) values have been determined by degenerate four wave mixing (DFNN) measurements for several new polymers prepared by condensation of tetraaminobenzene with a variety of bisalkylaminovinyldichloroquinones. By control of reaction c9Vitions, both open chain and fully fused ring polymers have been prepared and characterized. Comparable x(3) values (typically in the range 7 X 10 to 4 X 10 esu at 532 nm) are observed for the two forms of the polymer suggesting comparable electron delocalization lengths in the two forms. This observation is, in turn, suggestive of the importance of protonation effects in these nitrogen containing polymers. Derivatization with the vinylamine substituents not only affects polymer solubility and optical properties but also influences condensation polymerization kinetics. Open chain polymers of moderately high molecular weight can be prepared by reaction of the monomers in dimethylformamide am at ambient temperatures. The results for aminovinyl polymers are compared briefly with the results obtained for other ladder polymers prepared in our laboratory.
