Aggregation, energy transfer and intramolecular charge transfer in donor-acceptor-donor BODIPY derivative lead to single component white light emission

A white light emitting single halochromic hydrazine bridged bis(3-pyrrolyl BODIPY) fluorophore

“…We also developed a method 32 to remove BF 2 units from BODIPYs and the resulting ligands have been used in coordination chemistry. Kauang et al reported two meso -pyridyl BODIPY derivatives coupled with naphthyl derivative 33 8 and coumarin derivatives 34 9 that showed white light emission behavior in their aggregate forms due to energy transfer and charge transfer by varying the solvent polarity, concentration, and excitation wavelength. However, the reports on WLE molecules based on BODIPYs are very few, and to the best of our knowledge, there is no example of a WLE molecule based on 3-pyrrolyl BODIPY.…”

A Joint Theoretical and Experimental Study on a Tetrazole‐Anchored BODIPY‐Based Dye at the Surface of TiO2 for Dye‐Sensitized Solar Cell Applications

“…[27] In the literature, while triphenylamine, carbazole, phenothiazine, and coumarin derivatives are often preferred for the donor part, porphyrin, pyridine, and perylene derivatives are among the suitable candidates for the acceptor part. [28][29][30] The BODIPY dye compound with a tetrazole ring dye was created for the first time in the current work. Elemental analysis, 1 H NMR, 13 C NMR, and FT-IR spectroscopy have all been used to describe compounds.…”

Pillararene‐Induced Intramolecular Through‐Space Charge Transfer and Single‐Molecule White‐Light Emission

“…[3] Incorporation of dual emission from the combination of locally-excited (LE) state emission and intramolecular through-bond charge transfer (TBCT) emission is an important way to generate SMWLE. [4] However, the regulation of the ratio between LE and TBCT emissions for achieving efficient SMWLE has always been a thorny issue due to insensitive TBCT to the surrounding environment, in other words, it is difficult to manipulate TBCT at the molecular level via external stimuli. Consequently, there is an urgent need to develop new strategies beyond traditional TBCT to build SMWLE.…”
