Abstract
1,3-Connected polyarylmethyl dendritic heptaradical was prepared by th e treatment of the heptaether precursor with lithium in THF followed b y oxidation of the resultant carboheptaanion using iodine in THF at lo w temperature. The magnetization studies of heptaradical in frozen THF , which were carried by SQUID at T = 2 - 10 K, indicate the S = 7/2 gr ound state.
