摘要：
A colorimetric probe of Pb2+ has been designed based on the mechanism that a supramolecular probe selectively recognized the Pb2+-induced conformational transition of G- quadruplexes. The probe exhibited high sensitivity and selectivity towards Pb2+, which enabled it to be practically used in detection of the Pb2+ level in a freshwater system.
