Merocyanine–triarylamine bichromophores are readily synthesized by sequentially Pd-catalyzed insertion–alkynylation–Michael–Suzuki four-component reactions. White-light emissive systems form upon aggregation in 1 : 99 and 0.1 : 99.9 vol% CH2Cl2–cyclohexane mixtures, ascribed to aggregation-induced dual emission (AIDE) in combination with partial energy transfer between both chromophore units as supported by spectroscopic studies.

一锅合成的白光发射双色团,通过聚集诱导的双发射(AIDE)和部分能量转移进行操作。

通过连续的Pd催化的插入-炔基化-Michael-Suzuki四组分反应可以轻松合成花青-三芳基胺双发色团。聚集在1:99和0.1:99.9 vol%的CH 2 Cl 2-环己烷混合物中形成白光发射系统,这归因于聚集诱导的双发射(AIDE),并结合了两个发色团之间的部分能量转移(如光谱法所支持)学习。
