资源简介:
A three-dimensional supramolecular framework containing both left- and right-handed helixes, {[Zn(TTPA)Cl2]·1.63H2O}n (1), has been converted to a novel octanuclear cluster containing a metal–organic framework, [Zn8(ptptp)6Cl2](ClO4)2·4CH3OH·2H2O (1b), induced by ligand rearrangement during a solvothermal process. The luminescent properties of 1b indicate that the material can act as a selective probe toward Pb2+ and Cr2O72–.
