摘要

The unique structural attributes inherent to D 2 d-symmetric rigid tetraarylbimesityls render their close packing in the solid state difficult. We have exploited the indisposed tendency of such modules based on the bimesityl scaffold toward crystallization to design a novel class of amorphous functional materials with high glass transition temperatures and thermal stability (T d> 400° C). It is shown that a variety of 2-and 4-fold anthracene-functionalized ...
