摘要

合成了四苯基亚乙基取代的邻苯二甲腈和相应的亚酞菁。单取代和二取代邻苯二甲腈可以通过典型的SNAr反应制备。邻苯二甲腈的晶体结构表明，大体积的四苯乙烯部分抑制了分子间的[式：见正文]-[式：见正文]相互作用。通过硼模板化邻苯二甲腈的大环化反应，获得了在周边和轴向位置被四苯乙烯取代的亚酞菁。酞菁在THF/水混合溶剂中表现出典型的聚集诱导发射行为，而亚酞菁的荧光强度随着水含量的增加而降低。

Synthesis and photophysical properties of subphthalocyanine substituted with tetraphenylethylene moieties

Tetraphenylethylene-substituted phthalonitriles and corresponding subphthalocyanines have been synthesized. Mono- and di-substituted phthalonitriles could be prepared by a typical SNAr reaction. The crystallographic structures of phthalonitriles indicated that intermolecular [Formula: see text]-[Formula: see text] interactions were suppressed by the bulky tetraphenylethylene moieties. Subphthalocyanines substituted with tetraphenylethylenes at peripheral and axial positions were obtained by boron-templated macrocyclization of phthalonitriles. Phthalonitriles showed typical aggregation-induced-emission behavior in THF/water mixed solvents, while fluorescence intensities of subphthalocyanines were decreased with increasing water content.
