Heterogeneous macrocycles with fluorenone and fluorenol functional groups are synthesized by two facile methods involving post-modification on the macrocycles and one-pot co-cyclization from different monomers. Significantly, benefitting from the well-matched absorption/emission spectra and close distance of fluorenone/fluorenol moieties, the obtained heterogeneous macrocycles exhibit intriguing intramolecular energy transfer (ET) and fluorescence enhancement.
具有芴酮和芴醇官能团的杂化大环通过两种简便的方法合成,包括大环的后修饰和不同单体的一锅共环化。值得注意的是,得益于芴酮/芴醇部分的吸收/发射光谱良好匹配和近距离,所得杂化大环表现出有趣的分子内能量转移(ET)和荧光增强。
