The invention describes the synthesis of a panel of novel carbon-carbon linked carboranyl-containing 5,10,15,20-tetraphenylporphyrins bearing 25 44% boron by weight. In certain embodiments, a phenyl porphyrin compound has a carboranyl group attached to the phenyl group by a carbon-carbon linkage, wherein the phenyl group corresponds to the following formula ##STR00001## where R7 through R11 are hydrogen, a carboranyl group, or are selected from the group consisting of hydroxyl, NMe.sub.3.sup.+, PMePh.sub.2.sup.+, PO(OH).sub.2, SO.sub.3H, COOH, and NH.sub.2. In this embodiment, the carboranyl group is attached to the phenyl group by a carbon-carbon linkage, either one or two of R7 through R11 are other than hydrogen; and the phenyl porphyrin compound contains at least one phenyl group having at least one of said carboranyl groups.
