摘要

A novel hydrophilic copolymer P(NI-HEMA) containing the pendant group of naphthalimide moiety has been prepared. In the aqueous buffer solution, its film on the glass substrate shows an obvious fluo-rescanca change and excellent linear relevance in the pH range of 5.8--8.0. Specifically, using the is- obestic point at 406 nm as excitation wavelength can avoid the UV irradiation and the tedious calibra-tion process. The film stability and hydrophilicity of copolymer P(NI-HEMA) were studied. Because of the easy synthesis, low price and high linear relevance to pH, the hydrophilic chemosensor film of P(NI-HEMA) could be potentially applied as a low-cost pH indicator for high-throughput bioprocessing in microreactors.
