“…63 BF 2 hydrazone complexes ( 24 ; BODIHY) exhibit enhanced emission in the solid state and can act as solid‐state acid/base sensors when appropriately substituted 64. In addition, 2‐aniline‐benzimidazole coordinates boron, thus leading to the complex 25 but no photophysical studies have been reported 65. Another recent trend is the chemical modification of familiar fluorophores such as indigos or coumarins to provide chelating sites for efficient boron complexation.…”

Multidisciplinary research on novel organic luminescent dyes is propelled by potential applications in plastic electronics and biomedical sciences. The construction of sophisticated fluorescent dyes around a tetrahedral boron(III) center is a particular approach that has fueled the creativity of chemists. Success in this enterprise has been readily achieved with simple synthetic protocols, the products of which display unusual spectroscopic behavior. This account is a critical review of recent advances in the field of boron(III) complexes (excluding BODIPYs and acetylacetonate boron complexes) involving species displaying similar coordination features, and we outline their potential development in several disciplines.

Benzimidazole-Based N,O Boron Complexes as Deep Blue Solid-State Fluorophores

Benzimidazole-based boranils were designed and synthesized in order to assess the influence of halogen substituents on their optoelectronic properties. All compounds are photoluminescent in solution and solid state. Compared to the free ligands, the new boranils emit at a lower wavelength, by elimination of the excited-state intramolecular proton transfer observed with the ligands. In the solid state, some of the boranils exhibit a deep blue emission, presenting Commission Internationale de l’Éclairage (CIE) coordinates with an x-component of less than 0.16 and a y-component smaller than 0.04, highly desired values for the development of blue emitting materials.

“…63 BF 2 ‐Hydrazon‐Komplexe ( 24 ; BODIHY) zeigen eine verstärkte Emission im festen Zustand und können bei entsprechender Substitution als Säure/Base‐Sensoren im Festzustand fungieren 64. Zudem koordiniert 2‐Anilinbenzimidazol an Bor und führt zum Komplex 25 , für den jedoch keine photophysikalischen Eigenschaften beschrieben wurden 65. Ein weiterer neuerer Trend ist die chemische Modifizierung von gängigen Fluorophoren, wie Indigo‐ oder Cumarinfarbstoffen, um Koordinationsstellen für eine effiziente Komplexierung mit Bor zu erzeugen.…”

Die multidisziplinäre Forschung zu neuen organischen Lumineszenzfarbstoffen wird durch mögliche Anwendungen in der Kunststoffelektronik und Biomedizin vorangetrieben. Die Anordnung ausgeklügelter Fluoreszenzfarbstoffe um ein tetraedrisches Bor(III)‐Zentrum herum ist eine besondere Herangehensweise, die die Kreativität der Chemiker herausfordert. Erfolgreich sind dabei einfache Synthesemethoden, die zu Produkten mit ungewöhnlichem spektroskopischem Verhalten führen. Dieser Kurzaufsatz liefert eine kritische Betrachtung neuerer Fortschritte auf dem Gebiet solcher Bor(III)‐Komplexe (unter Ausschluss von BODIPY‐Verbindungen und Acetylacetonat‐Bor‐Komplexen), die Spezies mit ähnlichen Koordinationsmerkmalen umfassen, und prognostiziert die mögliche Entwicklung dieser Komplexe in verschiedenen Fachbereichen.
