Abstract

AbstractA new rhenium(I) complex, Re(CO)3Cl(aeip) [where aeip =2‐(anthracen‐9‐yl)‐1‐ethyl‐imidazo[4,5‐f][1,10]phenanthroline], was designed and synthesized as a luminescence probe under visible light excitation at 410 nm for detection of singlet oxygen (1O2) in aqueous media. The new complex can specifically react with 1O2 in neutral and alkaline media, which results in remarkable luminescence enhancements, with 8‐ and 18.7‐fold increases in the luminescence quantum yields, respectively. The visible light excitation may allow the complex to be useful for biosystems. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2008)
