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 similar to 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.
