合成了由噻吩、乙炔和乙烯亚基按72π、108π、144π和180π电子体系排列组成的大环化合物，并分析了它们的单光子和双光子吸收性质.增加π-共轭表明双光子吸收截面增加，在可见光谱区的幅度高达100 000 GM。
Giant π-conjugated macrocycles composed of thiophene, acetylene, and ethylene subunits arranged as 72π, 108π, 144π, and 180π electron systems were synthesized and analyzed for their one- and two-photon absorbance properties. Increasing π-conjugation showed an increase in the two-photon absorption cross section with magnitudes as high as 100 000 GM in the visible spectral region.
