摘 要:以对苯醌(P-benzoquinone)、1,4-萘醌(1,4-Naphthoquinone)和2,9,16,23-四氨基酞菁锌为前体合成了两种新型的共价有机框架(P-ZnPc COF、N-ZnPc COF)。利用FT-IR、UV-Vis对前体和产物进行表征。结果表明,相比较于2,9,16,23-四氨基酞菁锌,P-ZnPc COF和N-ZnPc COF中属于氨基的振动吸收峰消失,Q带与2,9,16,23-四氨基酞菁锌相比蓝移了14 nm。1H NMR、N2吸脱附和产物结构表征。结果表明,P-ZnPc COF和N-ZnPc COF均为孔径2.02 nm的多孔结构,可以储存气体。热重和循环伏安法测试表明P-ZnPc COF和N-ZnPc COF不仅具有优异的热稳定性,而且满足能带间隙规则,可以作为染料敏化剂应用。

Abstract:Two series of compounds with novel covalent organic frameworks were synthesized using P-benzoquinone, 1,4-naphthoquinone and 2,9,16,23-tetraamino phthalocyanine zinc as precursors. The precursors and products were characterized using FT-IR, UV-Vis. The results showed that, compared with 2,9,16,23-tetraamino zinc phthalocyanine, the vibration absorption peaks belonging to amino groups in P-ZnPc COF and N-ZnPc COF disappeared and their Q bands are similar to those of 2,9,16,23- zinc tetraaminophthalocyanine with a blue shift of 14 nm. The structure of the product was characterized by 1H NMR and N2 absorption and desorption. The results showed that both P-ZnPc COF and N-ZnPc COF were porous structures with a pore size of 2.02 nm, which could be used for storing gas. Experimental data from thermogravimetry and cyclic voltammetry testing showed that P-ZnPc COF and N-ZnPc COF not only had excellent thermal stability, but also met the band gap rules and could be used as dye sensitizers.
