寻找构建晶体多组分共价有机骨架（COFs）的新方法已成为一个重要的研究热点。在这里，我们报道了三种新型COFs的合成，其中含有均匀和非均匀分布的pi共轭脱氢苯环烯（DBA）顶点单元。将c -3-对称型DBA儿茶酚单体与c -2-对称型芘-2,7二苯丙酮酸（PDBA）反应，得到3种COFs，分别为Py-DBACOF 1、Py-DBA-COF 2和py - pv -DBA- cof。这三种材料都是高度结晶的，在固态下显示出独特的发光特性。
Finding new ways to construct crystalline multiple-component covalent organic frameworks (COFs) has become an important focus. Herein we report the synthesis of three novel COFs containing a homogeneous and heterogeneous distribution of pi-conjugated dehydrobenzoannulene (DBA) vertex units. The COFs were synthesized by reacting different tatios of C-3-syrninetric DBA catechol, monomers with C-2-symmetric pyrene-2,7dibotonic acid (PDBA) to yield three COFs, Py-DBACOF 1, Py-DBA-COF 2, and Py-MV-DBA-COF. All three materials are highly crystalline and display unique luminescent properties in the solid state.
