The bulky ortho-brominated aryl groups are implanted to create nonplanarity around amino center. Thus, the effective conjugation length to the protonation site is shortened and the energy gap between neutral and protonated forms is narrowed. The protonation can only occur at the nitrogen atom of the benzothiazole and the temperature variation disturbs the equilibrium between the neutral and monocation and the reverible thermochromic effect can thus be achieved.
