手性联萘酯-芘在光激发下的手性聚合发光：来自手性聚合发光起源的比较 **解析**：该文本涉及化学领域的专业术语，其中“CPL”表示圆二色性荧光（Circularly Polarized Luminescence），“monomer-origin”表示单体起源，“ester”表示酯基。因此，该文本的准确翻译应该是“手性联萘酯-芘在光激发下的手性聚合发光：来自手性聚合发光起源的比较”。

Two chiral binaphthyl (BNp) derivatives bearing oppositely oriented ester linkers to two pyrene (Py) moieties [(R)/(S)-1 and (R)/(S)-2] enabled Py-origin circularly polarized luminescence (CPL), magnetic CPL (MCPL), and circular dichroism (CD). (R)-1 that exhibited (-)-sign CD showed (+)-sign Py-excimer CPL but did not exhibit MCPL. Conversely, (R)-2, with (-)-sign CD, did not show excimer-origin CPL, but exhibited clear Py-monomer MCPL.
两个手性联萘（BNp）衍生物带有两个芘（Py）基团的相反定向酯键链接[(R)/(S)-1 和 (R)/(S)-2]，使 Py 起源圆偏振发光（CPL）、磁 CPL（MCPL）和圆二色性（CD）成为可能。（R）-1 表现出（-）-符号 CD 显示（+）-符号 Py 齐聚物 CPL，但不显示 MCPL。相反，（R）-2，具有（-）-符号 CD，没有显示齐聚物起源 CPL，但表现出明显的 Py 单体 MCPL。
