摘要

A series of four asymmetrically aryl-substituted 9, 9'-spiro-9-silabifluorene (SSF) derivatives, 2, 2'-di-tert-butyl-7, 7'-diphenyl-9, 9'-spiro-9-silabifluorene (PhSSF), 2, 2'-di-tert-butyl-7, 7'- dipyridin-2-yl-9, 9'-spiro-9-silabifluorene (PySSF), 2, 2'-di-tert-butyl-7, 7'-dibiphenyl-4-yl-9, 9'- spiro-9-silabifluorene (BPhSSF), and 2, 2'-di-tert-butyl-7, 7'-bis (2', 2''-bipyridin-6-yl)-9, 9'- spiro-9-silabifluorene (BPySSF) are prepared through the cyclization of the corresponding ...
