摘要

Four new rod-coil diblock molecules

which had well-defined para-phenylene oligomers (PPP

from biphenyl toquinquephenyl) as rigid segments and poly(ethylene oxide) (PEO

Mw ca. 750) as flexible segments

were synhesized. Thechemical structure and the number of repeating unit in PEO coil and PPP rod were characterized by 1H-NMR and MALDI-TOF mass spectromeny. The diblock oligomers showed good solubility in common organic solvents and aggregated in water as characterized by a blue shift in UV-vis absorption spectra

a red shift in emission spectra

quenching of the fluorescence and formation of the microfibrilla and fractal-like structures.The formation of different supramolecular structure meant that this effort might lead to commercial important highly organized functional materials.
