A series of 2,2'-di(heteroaryl)-9,9'-spirobifluorenes were prepared by employing Friedlander reaction of 2,2'-diacetyl-9,9'-spirodifluorene with a series of ortho-aminoarenecarbaldehydes. The compound 2,2'-di(benzo[b]-1,10-phenanthrolin-2-yl)-9,9'-spirofluorene (4e) showed a green light emission at 500 nm upon the excitation of the absorption at 374 nm while 2,2'-di(benzo[h]quinolin-2-yl)-9,9'-spirofluorene
通过使用 2,2'-二乙酰-9,9'-螺二芴与一系列邻氨基芳烃甲醛的弗里德兰德反应制备了一系列 2,2'-二(杂芳基)-9,9'-螺二芴。化合物 2,2'-di(benzo[b]-1,10-phenanthrolin-2-yl)-9,9'-spirofluorene (4e) 在 374 nm 而 2,2'-di(benzo[h]quinolin-2-yl)-9,9'-spirofluorene (4c), 2,2'-di(1,10-phenanthrolin-2-yl)-9, 9'-螺芴 (4d), 2-(benzo[h]quinolin-2-yl)-2'-(benzo[b]-1,10-phenanthrolin-2-yl)-9,9'-spirofluorene (4g) ),和 2-(1,10-phenanthrolin-2-yl)-2'-(benzo[b]-1,10-phenanthrolin-2-yl)-9
