We synthesized a phenazine analogue of triptycene acceptor, Trip-Phz, and found a honeycomb network of Trip-Phz with a wide 1D channel running through it. The interior surface of this channel was covered by the π electrons of Trip-Phz. Even though there was no interaction between Trip-Phz and an organic donor, tetrathiafulvalene (TTF), in their solutions, the honeycomb crystals of Trip-Phz exhibited a host–guest charge-transfer (CT) interaction with TTF, specifically a reversible adsorption/desorption of TTF with the appearance/disappearance of a CT band.

在三苯并噻吩类化合物的基于分子的蜂窝状晶格中形成的一维通道中可变的宿主-客体电荷转移相互作用

我们合成了三萜烯受体Tripphen的吩嗪类似物，并发现了Trip-Phz的蜂窝网络，其中有一个宽的1D通道贯穿其中。该通道的内表面被Trip-Phz的π电子覆盖。即使Trip-Phz与有机供体四硫富瓦烯（TTF）之间没有相互作用，Trip-Phz的蜂窝晶体仍显示出与TTF的主体-客体电荷转移（CT）相互作用，特别是可逆吸附TTF的脱附与CT条带的出现/消失。
