Most reported fluorescent probes have limitations in practical applications in living systems due to the strong autofluorescence background, construction of probes with near-infrared (NIR) fluorescence emission is an accessible approach for addressing this challenge. We here designed a NIR fluorescent probe for monitoring the endogenous production of H2S in living cells. The designed probe showed...
Naphthalene–naphthalene, anthracene–anthracene, and naphthalene–anthracene assemblies 1.1, 2.2, and 1.2 linked by 2-ureido-4{1H}-pyrimidinone binding module were synthesized. Fluorescence quenching and lifetime measurements demonstrate that the inner-assembly singlet energy transfer from naphthalene to anthracene in 1.2 occurs with the efficiency of ca. 89% and rate constant of ca. 9.8×10 8 ...
