| Abstract: | A relative rigid naphthalene-anthracene supramolecular ensemble has been designed and synthesized via 2-ureido-41H]-pyrimidinone quadruple hydrogen-bonded module.Steady-state and time-resolved fluorescence profiles demonstrate that the singlet-singlet energy transfer occurs effectively from naphthalene to anthracene moieties in ensemble UPNa· UPAn.The rate constant and efficiency for photoinduced energy transfer in ensemble UPNa·UPAn is much greater than that of theoretical calculation through Frster mechanism.Therefore,the singlet-singlet energy transfer process takes place via Frster mechanism and "through AADD quadruple hydrogen bond" mechanism in this ensemble. |
