Abstract

Abstract: Three sulfur‐containing pyran‐annulated perylene diimides (PDIs) were synthesized from commercially available PDIs through a nucleophilic substitution/cyclization reaction sequence. The as‐synthesized compounds were fully characterized by 1 H and 13 C NMR, and FT‐IR spectroscopy, as well as HRMS and TGA. The as‐prepared PDI derivatives exhibited significantly narrow HOMO–LUMO band gaps and high photochemical and thermal stability. Moreover, these materials exhibited quite different absorptions and emissions in dichloromethane, which were in agreement with the DFT‐calculated results. Abstract : PDI reporting for duty ! Three sulfur‐containing pyran‐annulated perylene diimides (PDIs) were easily synthesized from commercially available PDIs. Their interesting photophysical, electrochemical and molecular simulations properties were also investigated.
