Study on oxygen quenching processes of the excited state dendrimer molecules
Since the excited singlet state of the core stilbene in dendrimers G1-G4 has ca. 5-ns lifetime, oxygen quenched their excited singlet state producing the singlet oxygen. The efficiency of singlet oxygen production based on the quenching of the stilbene core is the highest in G4.
