Figure 3. High concentration band edge absorption as a function of solvent.

Figure 3

(a) The band edge absorption of 2,8-DPTZ-DBTO2 in a variety of solvents at 1 mM concentration. The hypsochromic shift unveils the nπ* nature of the low-energy absorption in this molecule. (b) Conversely for 3,7-DPTZ-DBTO2 at 1 mM concentration there is no significant shift in the absorption thus emphasising the mixed nature of the absorption in this system.
