The influence of the chemical structure of rigid star-shaped multipodes composed of an adamantane central core and short rigid branches on the glass formation and crystallisation is analysed. It was found that esters of 1,3,5,7-adamantanetetracarboxylic acid with various phenols (3a-c) and esters of 1,3,5,7-tetrahydroxyadamantane with various benzoic acid derivatives (4a-c) display both crystalline and glassy states with high glass transition temperatures and melting temperatures. These quantities strongly depend on the restriction of the rotational motions about the ester groups connecting the core and the branches.
