indicate that only up to 20 ps a weak TA signal from q-ax. is overlaid on a major TA signal from q-eq. Table . Determined emission lifetimes of PTZ-TRZ in toluene and THF solution. 𝜆𝜆 𝑞𝑞-𝑎𝑎𝑎𝑎. and 𝜆𝜆 𝑞𝑞-𝑒𝑒𝑞𝑞. are the peak positions of the emission bands of q-ax. and q-eq, respectively. 𝜏𝜏 q-ax. is the first lifetime componet of the emission of q-ax. 𝜏𝜏 q-eq. promt and 𝜏𝜏 q-eq. 𝑑𝑑𝑒𝑒𝑑𝑑𝑎𝑎𝑑𝑑𝑒𝑒𝑑𝑑 are the first and second lifetime components of the emission of q-eq., respectively.
