relaxation of DPAPT. That is, the photoexcited DPAPT can be initially
excited to the unrelaxed S1 state, and in succession an intramolec-
ular charge transfer takes place accompanying the diphenylamino
and triphenylamine group wag until it attains the most stable con-
formational geometry. According to our theoretical studies, the
potential energy curve as a function of twisting angle  and ϕ indi-
cates that the stable conformational geometry of the excited state
differentiates it from that of the ground state, which has mini-

As a general result for the DPAPT, it is concluded that the excited
state has a twisted intramolecular charger transfer character, which
displays strong fluorescent emission. More theoretical and experi-
mental studies of the twisting dynamics on terpyridine compound
are required.
