For Bl-NO DR (BC) diradical, a triplet ground state with a singlet-triplet energy gap of 419.4 cm -1 was observed and Bl-NO-NO T R (BC) yielded a quartet ground state with two doubletquartet energy gaps of 657.2 cm -1 and 364.3 cm -1 . Interestingly, the transmission spectra, shown in Figure , yields increasing number of degenerate peaks near Fermi energy on moving from mono-to tri-radical with a high conductance of the order of 10 -2 . Albeit small, the conductance shows an increases from 4.53 ×10 -2 to 4.94 ×10 -2 and 5.51 ×10 -2 on moving from mono-to di-and tri-radicals, respectively. Although, the expected increase in transmission at Fermi energy is again insignificant and conductance remains of the order of 10 -2 for mono-, di-and tri-radical systems. The increasing number of degenerate peaks near Fermi energy can be traced back to spatial distribution of frontier central subsystem molecular orbitals (shown in Figure ). For Bl-NO DR (BC), apart from the α-SOMO1/β-SUMO1, the other nearly-degenerate α-SOMO2/β-SUMO2 bears significant delocalization in the transport pathway. Similarly for Bl-NO-NO T R (BC), α-SOMO2/β-SUMO2 and α-SOMO3/β-SUMO3 are not entirely decoupled from the transport pathway, which reflects in the form of additional peaks in the T (E) near Fermi level.
