Popis:	1,3-Connected polyarylmethyl dendritic heptaradical was prepared by the treatment of the heptaether precursor with lithium in THF followed by oxidation of the resultant carboheptaanion using iodine in THF at low temperature. The magnetization studies of heptaradical in frozen THF, which were carried by SQUID at T = 2 - 10 K, indicate the S = 7/2 ground state.
