Abstract

A core-substituted naphthalene diimide (1) was self-assembled with (Et3P)2Pt·2TfO into a triangular structure (2) whereas an equilibrium mixture of triangular and dimer or tetramer was obtained with Pd(dppp)·2TfO and Pt(dppp)·2TfO. The triangular structure for 2 was supported theoretically by PM6 calculations and fully characterized by NMR spectroscopy and mass spectrometry. Complex 2, as compared to 1, shows a variable UV-Vis absorption and fluorescence as a function of solvent and is easily reducible during cyclic voltammetry. TEM and AFM imaging showed that 2 further self-assembles into nanostructures.
