摘要

本文报道了一系列bn -杂环熔合[6]螺旋烯的合成及其性质。bn -杂环的融合有利于扩大π共轭作用，提高第一激发态的吸收率和荧光效率。特别是双[6]螺旋BiBN-BiHC，由于其极高的ΦF（0.87）、较大的ε （5.47 × 104 M-1 cm-1）和良好的|glum| (2.06 × 10-3)，其圆偏振发光性能达到49.0 M-1 cm-1。

Brightening Up Circularly Polarized Luminescence of [6]Helicenes by Fusion with BN-Heterocycles.

We here disclose synthesis and properties of a series of BN-heterocycle-fused [6]helicenes. The fusion of the BN-heterocycle is helpful to extend π-conjugation and increase absorptivity and fluorescence efficiency of the first excited state. Especially, the double [6]helicene BiBN-BiHC shows outstanding circularly polarized luminescence performance with B_CPL up to 49.0 M^-1 cm^-1, owing to its very high Φ_F (0.87), large ε (5.47 × 10⁴ M^-1 cm^-1), and fairly good |g_lum| (2.06 × 10^-3).

期刊介绍： Organic Letters invites original reports of fundamental research in all branches of the theory and practice of organic, physical organic, organometallic,medicinal, and bioorganic chemistry. Organic Letters provides rapid disclosure of the key elements of significant studies that are of interest to a large portion of the organic community. In selecting manuscripts for publication, the Editors place emphasis on the originality, quality and wide interest of the work. Authors should provide enough background information to place the new disclosure in context and to justify the rapid publication format. Back-to-back Letters will be considered. Full details should be reserved for an Article, which should appear in due course.
