quantum yield of 0.35 (n = 2) was detected. Computational studies have been performed to provide additional insight into the structural and electronic properties of these supramolecular complexes. Theoretical results obtained are in good agreement with the experimental data, supporting the proposed structural motif. These studies also suggest that the observed efficient long-wavelength luminescence
