Photoisomerization and energy transfer in naphthalene-terminated stilbene dendrimers

Abstract

Naphthalene-terminated stilbene dendrimers, the largest stilbene dendrimers to date, underwent photoisomerization via highly efficient energy transfer from the dendron group to the core stilbene. It was also demonstrated that the energy transfer efficiency in these dendrimers may be controlled by light, utilizing trans-cis isomerization as the key photoreaction.
