摘要：

A novel PAMAM dendron designed as a wavelength-shifting bichromophore with 1,8-naphthalimide energy "donor" capable of absorbing light and efficiently transferring the energy to a focal Rhodamine 6G "acceptor" was synthesized and investigated. Moreover, the system was configured on the "fluorophore-spacer-receptor" format. Thus, the distinguishing features of FRET systems were successfully combined with the properties of photoinduced electron transfer and classical ring-opening sensor systems. The synthesized compound shows excellent signaling properties towards protons, Hg2+ and Fe3+ ions, therefore, the system is able to act as an one-output combinatorial logic circuit with four chemical inputs.
