Natural transition orbitals (NTOs) with occupied (holes) and unoccupied (electrons) pairs with a contribution higher than 25% for 12, presenting the nature of the absorption spectrum (6-31G(d,p)/B3LYP) with the contributions from the (pyrene/pyridyl/triazolyl) substituents. For each state, the respective values for the state, transition energy, and oscillator strength are listed.
