One-pot heteroannulation toward phosphaperylene diimides with high luminescence and out-of-plane anisotropy

摘要

P-heteroannulation on perylene diimides in one pot is presented. The resulting phosphaperylene diimides demonstrate unique molecular structures with an out-of-plane dipole moment of 8.10 D. Photophysical characterization reveals degenerated LUMO levels as low as -4.4 eV and remarkable absorption redshifts extending to 579 nm. High fluorescence quantum yields (phi(F)) of up to 94% make them promising photoluminescent materials.
