摘要

Dihydroxyoligophenylenes (HO-ArPh (m)-OHs) with 9, 9-dihexyl-2, 7-fluorene (Ar= Flu), 2, 5- dioctyloxy-1, 4-benzene (Ar= Dob), pyridine (Ar= Py), or thiophene (Ar= Th) rings were synthesized by the Suzuki coupling reaction. Absorption maxima (λmax) of HO-ArPh (m)- OHs shifted progressively toward long wavelengths due to the expansion of the π- conjugation system with an increase in the number of benzene rings. Deprotonation of the ...
