Article Synopsis
- A new PAMAM system was developed that uses a light harvesting antenna with yellow-green emitting donor units to absorb light and transfer energy to a Rhodamine 6G acceptor.
- The system is structured in a way that enables it to function as a molecular fluorescence probe, utilizing both electron transfer and pH-dependent absorption.
- This combination allows the antenna to act as a selective ratiometric pH fluorescence probe, making it useful for monitoring pH changes in complex solutions.
