This Letter describes the synthesis of a novel fluorescein-based derivative used as the fluorescence sensor for Pd2+ detection. The sensor can show highly selective and sensitive 'off-on' fluorescence response only in the presence of Cu2+ as a synergic trigger, which presents a new strategy for Pd2+ detection method.
