Novel truxene-based dipyrromethanes (DPMs): synthesis, spectroscopic characterization and photophysical properties

Year: 2024

Type: article

Abstract: For the first time, herein, we report the synthetic part of the truxene-centred mono-, di- and tri-substituted dipyromethanes (DPMs) in good yields (60–80%) along with their preliminary photophysical (absorption, emission and time resolved fluorescence lifetime) properties. The condensation reaction for assembling the required DPMs were catalyzed with trifluoroacetic acid (TFA) at 0 °C to room temperature (rt), and the stable dipyrromethanes were purified through silica-gel column chromatography. After successfully synthesizing these easy-to-make yet interesting molecules, they were fully characterized by means of the standard spectroscopic techniques ( 1 H NMR, 13 C NMR and HRMS). We are of the opinion that these truxene-based systems will be useful for diverse applications in future studies.
