25 September, 2014 - 08:17

Chem. Commun., 2014, Advance Article
DOI: 10.1039/C4CC05943C, CommunicationXu Liang, Soji Shimizu, Nagao Kobayashi
Peripheral substitution with electron-donating (push) and electron-withdrawing (pull) substituents caused a sizeable red-shift of the Q band absorption and fluorescence of subporphyrazine, and the red-shift was controlled by the push substituents.
