Abstract: Abstract Two triptycene-based diamines, 2,6-diaminotriptycene and 2,6-diaminotriptycene- 14-carboxylic acid, were synthesized and reacted with 4,4′-(hexafluoroisopropylidene) diphthalic anhydride (6FDA) to form three polyimides, denoted as 6FDA-DAT, 6FDA-DAT/DATCA (9:1) and 6FDA-DAT/DATCA (8:2). The last two carboxylic acid… read more here.
