Synthesis and Properties of Novel Spirobifluorene-Cored Dendrimers

Publication year: 2011 Source: Dyes and Pigments, Available online 21 December 2011 Huicai Ren, Qian Tao, Zhanxian Gao, Di Liu Two novel spirobifluorene-cored dendrimers containing polyphenylene dendrons with the carbazole (spiro-Cz) and cyano surface groups (spiro-CN) were synthesized and characterized. Both the dendrimers show good solubility in common organic solvents.Spiro-Czis amorphous even when it is obtained directly from organic solvents and an extremely high glass transition temperature of 332 °C is detected.
