A series of new carbazole-based luminophores (1-12) were synthesized and well characterized, which demonstrated aggregation-induced emission enhancement (AIEE) properties. The obtained experimental results demonstrated that the attachment of aromatic rotors to luminophore moieties would lead to the decreased quantum yields (measured in diluted solutions); the more rotors attached, the smaller the quantum yields tested. This further confirmed that the AIEE phenomena were caused by the restriction of the intramolecular vibrational and rotational motions in an indirect manner.
合成并充分表征了一系列基于咔唑的新型发光体（1-12），它们表现出聚集诱导发光增强（AIEE）特性。所获得的实验结果表明，将芳香族转子连接到发光体部分会导致量子产率降低（在稀释溶液中测量）；连接的转子越多，测试的量子产率越小。这进一步证实了AIEE现象是由分子内振动和转动运动的限制以间接方式引起的。
