摘要:Different structures and different Ag+-response behaviors of a pair of pyrene-based S-containing atropisomers, namely s-BSPPy and a-BSPPy, have been investigated. The calculated high rotation barrier indicates that the two atropisomers are non-interconvertible. In polar solvents, s-BSPPy exhibits excimer emission but a-BSPPy does not. Based on the X-ray structures and the DFT calculated intermolecular interactions, the excimer of s-BSPPy is suggested to take a non-parallel edge-to-face lambda-shaped geometry. Especially, s-BSPPy exhibits ratiometric excimer-off and monomer-on emission as a unique response to Ag+ in solutions, while no ratiometric Ag+-response was observed for a-BSPPy.
