Cucurbituril [7] thin film fluorescence sensor preparation method

The invention discloses a cucurbituril [7] thin film fluorescence sensor preparation method. The method mainly utilizes a photopolymerization method in chemical methods to bond the derived cucurbituril [7] and methyl methacrylate monomer onto the surface of methacrylic acid3-( trimethoxysilane) propyl ester silanized quartz glass through a polymerization process to obtain a cucurbituril [7] thin film fluorescence sensor. The method comprises three steps: to begin with, placing the quartz glass into piranha etching liquid to remove all of organic matters, then, placing the obtained quartz glassinto a NaOH concentrated solution for soaking to completely neutralize the acid on the surface so as to fully expose hydroxyl on the surface, rinsing the surface with distilled water until clean, andthen, carrying out silanization on the quartz glass; then, preparing a cucurbituril [7] thin film solution; and finally, contacting the quartz glass with the solution evenly, providing UV-irradiationto carry out photoinduced
