摘要：

Lowering temperature of solutions of poly(3-hexylthiophene-2,5-diyl) P3HxTh below -10 - -20 degrees C leads to decrease in signal intensity of aromatic-H and alpha-CH2 in H-1-NMR spectrum. A shift of the pi-pi* absorption band to a longer wavelength by 26-60 nm is also observed. These results are accounted for by aggregation of P3HxTh through intermolecular interaction of the pi-conjugated system.
