Published: May 2024

Three new distinct NIR α,α-NH-bridged BODIPY dimers were prepared by a direct nucleophilic substitution reaction. The synergistic effects of the nitrogen bridges and strong excitonic coupling between each BODIPY unit play major roles in enhancing the delocalization of an electron spin over the entire BODIPY dimers. The formed aminyl radical dimer showed an absorption maximum at 1040 nm.

facile access to -heteroaryl-fused bis-BODIPY scaffolds has been developed. A BODIPY dimer with an α,α-amine linker serves as a starting material to obtain pyrrole- and pyridine-fused BODIPYs, either by direct oxidation or by oxidative condensation with an aldehyde building block. Both species mark antipodal conjugative coupling conditions that result in distinct spectral outcomes.

Herein, we report the synthesis of novel dimeric urea-bridged BODIPY-carbohydrate conjugates, which display circularly polarized luminescence (CPL). The dimers are composed of diastereomerically pure, axially chiral (P or M) BODIPY monomers containing a pendant glucose (d- or l-) unit. The latter was intended to add chirality, biocompatibility, and enhanced water solubility and facilitate the chromatographic resolution of the intermediate atropisomers.

Article Synopsis
  • The study focuses on BODIPY derivatives with a rigid aromatic backbone that can form self-assemblies and aggregates.
  • It uses scanning tunneling microscopy (STM) and density functional theory (DFT) to directly visualize the self-assembled structures of three different BODIPY derivatives.
  • The findings indicate that the arrangement of intermolecular interactions affected the structure, with some derivatives forming lamellar and staggered structures, while others took on a head-to-tail configuration based on their functional group variations.

Synthesis, photochemical properties, liposomal encapsulation, and in vitro photodynamic activity studies of novel BODIPY dimer connected at positions and its brominated and iodinated analogs were described. UV-Vis measurements indicated that the dimeric structure of obtained BODIPYs did not significantly influence the positions of the absorption maxima. Emission properties and singlet oxygen generation studies revealed a strong heavy atom effect of brominated and iodinated BODIPY dimers, manifested by fluorescence intensity reduction and increased singlet oxygen generation ability compared to analog without halogen atoms.

Four BODIPY dyes (6a-6d) with electron-donating or electron-withdrawing groups at the -position were synthesized by the Sonogashira coupling reaction of 2,5-diethynylthieno[3,2-]thiophene with mono-iodo-BODIPY moieties. All compounds were fully characterized by H NMR and MALDI-TOF MS. Their photophysical and electrochemical properties were studied by UV-visible absorption spectroscopy, steady-state and time-resolved fluorescence spectroscopy, two-photon excitation spectroscopy and cyclic voltammetry.
