Synthesis, Photoluminescence, and Electroluminescence of Silicon Cardo and Spirosilabifluorene Derivatives

摘要

We have designed and synthesized a series of fluorene-based materials for organic light-emitting diodes (OLEDs). Particularly, 9,9-diphenyl-substituted fluorene (cardo), 9,9-spirobifluorene, and their silicon derivatives (silacardo and spirosilabifluorene) bearing electronic donor-acceptor substituent on 2- and 7- positions are characterized for photoelectronic characteristics.
