Strong fluorescence enhancement of 2-bromo-3-(1H-indol-3-yl)maleimide upon coordination to a Lewis-acidic metal complex
Abstract
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.
