摘要：
The two-photon excitation action cross-sections of four kinds of co-oligomers of thiophene and pyridine (e.g., Py-(Th)(n)-Py; Py = 2-pyridyl, Th = thiophene-2,5-diyl; n = 3, 4) and a copolymer constituted of alternating pyridazine and 4,4'-dihexyl- 2,2'-bithiophene units have been measured by using a reported value ((sigma(2PE) at 780 nm = 10 GM) of green fluorescent protein as the reference. The co-oligomers give sigma(2PE) values of 14-26 GM and the copolymer shows sigma(2PE) of 23 GM.
