  Applying the Oligomer Approach to Luminescent Conjugated Organoboranes

  摘要：

  A series of highly luminescent monodisperse fluoreneborane oligomers (n = 1-6) were prepared using a new iterative synthetic procedure that takes advantage of the highly selective and differential reactivity of bromoboranes with arylsilanes and arylstannanes. Cyclic and square wave voltammetry revealed a gradual decrease of the LUMO energy levels with increasing chain length, while absorption and emission data showed a bathochromic shift and increase in quantum efficiency. An extended conjugation length of n(ECL) = S was derived.

  Polystyrene was functionalized with luminescent fluorenyl- and carbazolylborane pendant moieties. Because of an interaction of the empty p orbital on boron with the extended pi-systems of fluorene or carbazole, the resulting polymeric materials exhibit intense blue emission with maxima in the range 390-420 nm. The solution quantum yields were 65% for the fluorene derivative and 68 and 11% for two different carbazole derivatives, respectively. The stability of the borylated polymers was enhanced by attachment of a bulky triisopropylphenyl group to each of the boron centers. Thus, the polymers were found to be stable for a period of over 1 month. Thermal stability up to ca. 250 degrees C was confirmed by thermogravimetric analysis.
