Breaking some of the bonds that connect the central N atom in 2T-N and 2T-7N to the rim, as shown in Fig. , is another way to reduce the molecular symmetry. Quite interestingly, breaking bonds in 2T-N quickly drives it from the region with inverted ST order to the normal region, while the opposite occurs for 2T-7N. As expected, the lowestlying singlet state acquires sizable intensity when one or two bonds are broken and the symmetry of the system reduced. Of course when all bonds are broken the D 3h symmetry is recovered and the lowest energy states are dark (see ESI, Sec. S4).
