英文摘要	A large triangular arylene-ethynylene macrocycle featuring unique circularly arranged -[D-pi-A](3)- electronic characteristics is designed and synthesized. The shape-persistent pi-conjugated backbone is composed of alternating electron-rich dialkoxyphenanthrene and electron-deficient dicyanodibenzo[f, h] quinoxaline units, connected by ethynylene linkers. The synthesis of such a special macrocyclic molecule is realized by employing a post-cyclization functional group installation strategy. The absorption and emission spectra of the macrocycle are found sensitively dependent on the solvent polarity. By virtue of a conjugated pi-scaffold and a cyclic -[D-pi-A](3)- motif, evident two-photon absorption (2PA) and two-photon excitation fluorescence properties are exhibited, with a 2PA cross section maximum of 3 x 10(3) GM determined by the Z-scan method.; National Natural Science Foundation of China [51473003, 21674001]; SCI(E); ARTICLE; 5; 737-742; 4
