Estimation of the effective conjugation length of oligo-p-phenylenes from specific refractive index increments of solutions

SummaryAn unusually strong molecular weight dependence of the specific refractive index increment which has been reported for solutions of oligomers (M < 103) of p-2-methyl phenylene is attributed to the exaltation of polarizability of phenylene units. The saturation length is estimated to be ls≅...

Zusammenfassung:SummaryAn unusually strong molecular weight dependence of the specific refractive index increment which has been reported for solutions of oligomers (M < 103) of p-2-methyl phenylene is attributed to the exaltation of polarizability of phenylene units. The saturation length is estimated to be ls≅ 6 phenylene units.
