The New Method of Surface-Assisted COF Synthesis for Optical Sensor Modification

Abstract

Covalent organic frameworks (COFs) are an emerging class of crystalline networks that are covalently built from organic components and featured by merits of low density, well-defined pore aperture, large surface area, inherent porosity, facilely tailored functionality, and ordered channel structure. Among other applications, COF compounds can be utilized for CO2 detection. It Is known that the preparation of COFs compounds is commonly associated with hard experimental conditions (high pressure, inert atmosphere, and high temperature). In this work, we suggest an alternative method of COFs under normal pressure and temperature. The experimental concept implements the surface-assisted COF growth. The created surface-immobilized COF structures were subsequently used for measurement of CO2 presence.
