Organic polymers with ordered functional groups often exhibit enhanced physical properties compared to amorphous polymers with randomly orientated functional groups. We studied the metallopolymers synthesized with zinc salts and 2,5-disubstituted terephthalic acid bearing flexible side chains exhibited either layered mesophase depending on the lengths and flexibilities of the side chains. However, in metallopolymers synthesized using the solvothermal reaction, the influences of large-sized pendant groups on their mesophase behavior and resulting physical properties have not been fully understood yet. Here, we reported a series of mesophase metallopolymers, ZnCZm bearing oxyalkyl-9H-carbazole groups. Despite the large size of the pendant carbazole groups at the end of the alkyl spacers, the ZnCZm metallopolymers exhibit a layered mesophase structure. Their layer distances and glass transition temperatures vary systematically with the length of the oxyalkyl spacers. |
