We report the synthesis and systematic description of a series of five para-substituted phenoxy-BsubPcs including their characterization in the crystal state. The nature of the substituents on the phenoxy molecular fragment was chosen so as to vary both the size and electronegativity: specifically with increasingly bulky para-alkyl groups from hydrogen to tert-octyl and a single electronegative substitute (F). Examination of the arrangement of the phenoxy-BsubPcs within single crystals allows us to place each into one of the two categories. The first, which contains all but one of the derivatives, has a repeating motif which is made up of dimers of the BsubPc molecular fragments. The second, containing only the derivative possessing the large tert-octyl substituent, is characterized by the formation of ribbons instead of dimers of the BsubPc fragment. Regardless of motif the arrangement of the BsubPc molecular fragments was found to be convace–concave.
我们报告了五个对位取代苯氧基-BsubPcs 系列的合成和系统描述,包括它们在晶体状态下的特征。我们选择了苯氧基分子片段上取代基的性质,以改变其大小和电负性:特别是从氢到叔辛基的对位烷基和单一电负性取代基(F)。通过观察单晶体中苯氧基-BsubPcs 的排列,我们可以将每种苯氧基-BsubPcs 分为两类。第一类包含除一种衍

生物,具有一个由 BsubPc 分子片段的二聚体组成的重复图案。第二类只包含具有大的叔辛基取代基的衍
生物,其特点是形成带状而不是 BsubPc 片段的二聚体。研究发现,无论采用哪种模式,BsubPc 分子片段的排列都是呈卷曲凹形的。
