Strong Fluorescence Enhancement of 2-Bromo-3-(1H-indol-3-yl)-maleimide upon Coordination to a Lewis-acidic Metal Complex

Zusammenfassung

The emission intensity of an indolyl maleimide derivative increases ∼80-fold by reversible coordination to (1,4,7,11-tetraazacyclododecane)zinc(II), which makes the system a promising new signalling motif for molecular sensors.
