摘 要:以對苯醌(P-benzoquinone)、1,4-萘醌(1,4-Naphthoquinone)和2,9,16,23-四氨基酞菁鋅為前體合成了兩種新型的共價(jià)有機框架(P-ZnPc COF、N-ZnPc COF)。利用FT-IR、UV-Vis對前體和產(chǎn)物進(jìn)行表征。結果表明,相比較于2,9,16,23-四氨基酞菁鋅,P-ZnPc COF和N-ZnPc COF中屬于氨基的振動(dòng)吸收峰消失,Q帶與2,9,16,23-四氨基酞菁鋅相比藍移了14 nm。1H NMR、N2吸脫附和產(chǎn)物結構表征。結果表明,P-ZnPc COF和N-ZnPc COF均為孔徑2.02 nm的多孔結構,可以?xún)Υ鏆怏w。熱重和循環(huán)伏安法測試表明P-ZnPc COF和N-ZnPc COF不僅具有優(yōu)異的熱穩定性,而且滿(mǎn)足能帶間隙規則,可以作為染料敏化劑應用。 |

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. |
