Efficient luminescence from easily prepared fluorine–boron core complexes based on benzothiazole and benzoxazole
摘要:
A series of brightly luminescent fluorine boron cored complexes were synthesized from readily available precursors in high yield and were structurally characterized. The molecular structures were based on the benzothiazole and benzoxazole frameworks. The emission maxima of these fluorine boron cored complexes spanned 70 nm in the visible spectrum from 450 nm (blue) to 520 nm (green). The photoluminescence quantum yields ranged from 0.16 to 0.8 in dichloromethane at room temperature. Altering the chelating position on the naphthalene ring provides a means to tailor the optical properties of the complexes. (C) 2014 Elsevier Ltd. All rights reserved.

A new tunable luminescent family of heterocyclic aromatic compounds containing boron has been prepared and characterized through NMR spectroscopy, mass spectrometry, absorption and fluorescence spectroscopy as well as structural study using single crystal X-ray crystallography. Spectroscopic properties of the new compounds were also studied using DFT and TDDFT computational models that showed very

The invention provides compounds having utility inter alia as electron transport materials in optical light emitting diodes (OLEDs) and of the formula (I), (Il) or (III). Embodiments of the compounds when incorporated as electron transport layers in OLEDs exhibit a greater current density for a given voltage than corresponding devices where the electron transport material is aluminium quinolate.
