A novel macrocycle co-crystals (MCCs) that consisting of electron-rich phenanthrene[2]arene (P2) and electro-deficient 1,2,4,5-tetracyanobenzene (TCNB) has been prepared. The formed MCCs exhibited specific selective vapochromic response to benzene among five aromatic hydrocarbons volatile organic compounds. Single-crystal structures and PXRD analyses confirmed that this specific selective vapochromic behavior was mainly attributed to the excellent benzene adsorption capacity of P2, leading to dissociation of P2@TCNB co-crystals and CT interactions which affecting its optical features.

对苯具有特定选择性汽致变色作用的大环电荷转移共晶


制备了一种由富电子菲[2]芳烃（P2）和缺电1,2,4,5-四氰基苯（TCNB）组成的新型大环共晶（MCC）。形成的MCC对五种芳香烃挥发性有机化合物中的苯表现出特定的选择性气致变色响应。单晶结构和PXRD分析证实，这种特定的选择性气致变色行为主要归因于P2优异的苯吸附能力，导致P2@TCNB共晶解离和CT相互作用，从而影响其光学特性。
