Controllable supramolecular self-assemblies (rods-wires-spheres) and ICT/PET based perylene probe for palladium detection in solution and solid state

Abstract

The control over the self-assembly of bay functionalized perylene diimide and response of these self-assembled materials towards analyte in mixed aqueous-organic media is important to consider potential of such intriguing dye family in supramolecular chemistry. Herein, we have designed and synthesized allylcarbonate-functionalized perylene diimide AC-PDI which shows solvent dependent supramolecular nanostructures and could readily self-assemble into nanorods of tens of µm in length in CH3CN but the length of rods drammatically decreased to 0.8-1.2 µm in 50% H2O:CH3CN (1:1, v/v) mixture. Interestingly, AC-PDI self-assemble into nanowires of several tens of µm in length in 30% H2O:DMSO mixture and form only nanospheres in ethyl acetate. AC-PDI can be used as near-infrared (NIR) colorimetric (λabs 685 nm) and fluorescent (λem 530/570 nm) probe for selective detection of Pd0 [LOD = 39 nM (UV); 45 nM (FI)]. Furthemore, TLC strips coated with AC-PDI probe, could detect 0.58 pg/cm2 of Pd0 in the solid state. The mechanism of interaction of AC-PDI with Pd0 has been confirmed by 1H NMR titration, kinetic and morphological studies.
