Self-Assembly of an Octanuclear Platinum(II) Tetragonal Prism from a New Pt^II₄ Organometallic Star-Shaped Acceptor and Its Nitroaromatic Sensing Study

Abstract

[2 + 4] self-assembly of a pyrene-functionalized Pt(II)(8) tetragonal prism (2) is achieved using a newly designed star-shaped organometallic acceptor (1) in combination with an amide-based "clip" donor (L). The propensity of this prism (2) as a selective sensor for nitroaromatics (2,4-dinitrotoluene, 1,3,5-trinitrotoluene, and picric acid), which are the chemical constituents of many commercial explosives, has been examined.
