実験手順

In the copper binding embodiment of the invention, the chemosensor, (12), comprises 8-HQ moiety as a binding site and BODIPY as a reporting group. (10) was prepared from styrene by bromination, conversion to the bromoazide which was eliminated to give azidostyrene; on heating (10) was isolated. (11) was synthesized by (10)'s reaction with methoxytetralone in the presence of NaH. In a one-pot three-step conversion, 8-HQ-2-carbaldehyde was condensed with pyrrole (11) to afford the dipyromethane which was oxidized to the dipyrromethene and reaction with BF3-OEt2 gave chemosensor (12) (FIG. 12, Scheme 2).
