  We suggest the application of nitronylnitroxide substituted with methyl group
and 2,2,6,6-tetramethylpiperidin organic radicals as 1/2-spin qubits for
self-assembled monolayer quantum devices. We show that the oscillating
cantilever driven adiabatic reversals technique can provide the read-out of the
spin states. We compute components of the $g$-tensor and dipole-dipole
interaction tensor for these radicals. We show that the delocalization of the
spin in the radical may significantly influence the dipole-dipole interaction
between the spins.
