Abstract
Stepwise locking of phenyl rings of tetraphenylethene increases the emission efficiency of luminogen solutions gradually, thus verifying the restriction of intramolecular rotation (RIR) mechanism of the aggregation induced emission phenomenon. The emission of the luminogen with one "O" bridge could be tuned reversibly in solid state through repeated heating and grinding.
摘要
逐步锁定四苯乙烯的苯环会逐渐提高发光体溶液的发射效率，从而验证了聚集诱导发光现象的分子内旋转（RIR）机制的限制。通过反复加热和研磨，可以在固态下对具有一个“O”桥的发光体进行可逆的发射调谐。
