Abstract
A series of bis[N,N-di-(4-methoxylphenyl)amino]arene dications 12+–32+ have been synthesized and characterized. Their electronic structures were investigated by various experiments assisted by theoretical calculations. It was found that they are singlets in the ground state and that their diradical character is dependent on the bridging moiety. 32+ has a smaller singlet–triplet energy gap and its excited triplet state is thermally readily accessible. The work provides a nitrogen analogue of Thiele’s hydrocarbon with considerable diradical character.

- 11The C41–C42 bond (1.430(2) Å) is much longer than the bond of C34–C35 (1.356(3) Å), which is probably caused by recovery of the aromaticity of the peripheral benzene ring of naphthalene.

- 12bThe multireference methods other than TD-DFT more properly describe the electronic configurations of the open-shell singlet state of diradicals. However the computational costs of multireference methods are quite high and it is unfeasible for the current study. Nonetheless, TD-DFT methods have been previously shown to be useful in estimating absorption bands of species with diradical character. For latest references, see:

- 13It is worth noting that the most stable electronic states for 12+ and 22+ are open-shell singlets in the gas phase (Table S2, SI). Such a difference between calculation and experimental observations may be ascribed to the counter ion effect. For example, bis(triphenylamine)dications with arylene/vinylene-conjugated bridges were reported to be closed-shell singlets in the solid state but their open-shell singlets have the lowest energy in the gas phase.

- 15bCalculations show that 32+ has similar diradical character (y=0.85) to its hydrocarbon analogue with N replaced by C atoms (32+-CA, y=0.89) with a slightly higher ΔES–T (32+ −1.47; 32+-CA −0.93 kcal mol−1). Attempted optimization of hydrocarbon analogues of 12+ and 22+ at the various levels by using the broken-symmetry method did not converge to open-shell singlets (OS) but to closed-shell singlets instead.
