Effects of Methyl Substitution on the Structure and Rotational Barrier in the Rigid-Rod Polymer Poly(p-phenylenebenzobisthiazole)

Abstract: X-ray crystallographic and ab initio molecular orbital analyses are presented for three model compounds of methyl-substituted poly(p-phenylenebenzobisthiazole), PBZT, where monomethyl and dimethyl substitutents are located on the phenylene moiety. The barrier to phenylene rotation, a factor considered to be important for an understanding of the mechanical, electronic, and nonlinear optical properties of PBZT and related rigid-rod heterocyclic polymers, is calculated for each compound. Ortho substitution with a… Show more
