Abstract

In this work, we investigated the morphology and crystallinity changes of a [Formula: see text]-ketoenamine COF, Tp-BD(Me) 2 (Tp=1,3,5-triformylphloroglucinol, BD(Me) 2 =3,3[Formula: see text]-dimethyl-[1,1[Formula: see text]-biphenyl]-4,4[Formula: see text]-diamine), with different reaction time and temperatures. Powder X-ray diffraction (PXRD) and Fourier-transform infrared (FTIR) spectra tests confirmed the synthesis of Tp-BD(Me) 2 , which has a specific [Formula: see text]-ketoenamine linkage and a probable eclipsed stacking mode. At a reaction temperature of 50[Formula: see text]C, the morphology of Tp-BD(Me) 2 underwent a progressive process of growing, extending and splitting. The band gaps of the Tp-BD(Me) 2 obtained with the reaction time of 18–24 h were calculated near 2.0 eV. The BET surface areas of the Tp-BD(Me) 2 were around 400–600 m 2 /g. It is not an optimal choice if the reaction temperature is below 50[Formula: see text]C, which could cause a low crystallinity and disordered morphology. However, slightly improving the reaction temperature to 60[Formula: see text]C is beneficial for generating high-crystallinity Tp-BD(Me) 2 .

β-酮胺COF Tp-BD(Me)2的合成与表征

本文研究了[式:见文]-酮胺COF, Tp-BD(Me) 2 (Tp=1,3,5-三甲酰基间苯三酚，BD(Me) 2 =3,3[式:见文]-二甲基-[1,1[式:见文]-联苯]-4,4[式:见文]-二胺)在不同反应时间和温度下的形态和结晶度变化。粉末x射线衍射(PXRD)和傅里叶变换红外(FTIR)光谱测试证实了Tp-BD(Me) 2的合成，其具有特定的[公式:见文]-酮胺键和可能的重叠堆叠模式。在反应温度为50℃时[公式:见文]C, Tp-BD(Me) 2的形态经历了生长、延伸和分裂的渐进过程。反应18 ~ 24 h得到的Tp-BD(Me) 2的带隙在2.0 eV附近。Tp-BD(Me) 2的BET表面积约为400 ~ 600 m2 /g。如果反应温度低于50℃[公式:见文]C，则不是最佳选择，这可能导致结晶度低，形貌混乱。但将反应温度略微提高到60℃[公式:见文]有利于生成高结晶度的Tp-BD(Me) 2。

期刊介绍： Functional Materials Letters is an international peer-reviewed scientific journal for original contributions to research on the synthesis, behavior and characterization of functional materials. The journal seeks to provide a rapid forum for the communication of novel research of high quality and with an interdisciplinary flavor. The journal is an ideal forum for communication amongst materials scientists and engineers, chemists and chemical engineers, and physicists in the dynamic fields associated with functional materials. Functional materials are designed to make use of their natural or engineered functionalities to respond to changes in electrical and magnetic fields, physical and chemical environment, etc. These design considerations are fundamentally different to those relevant for structural materials and are the focus of this journal. Functional materials play an increasingly important role in the development of the field of materials science and engineering. The scope of the journal covers theoretical and experimental studies of functional materials, characterization and new applications-related research on functional materials in macro-, micro- and nano-scale science and engineering. Among the topics covered are ferroelectric, multiferroic, ferromagnetic, magneto-optical, optoelectric, thermoelectric, energy conversion and energy storage, sustainable energy and shape memory materials.
