Structuration of pH-responsive fluorescent molecules on surfaces by soft lithographic techniquesDedicated to Prof. J. Font in honor of his 70th birthday

Two different soft lithographic techniques (LCW and μCP) have been successfully used for the structuration of fluorescent pH-responsive molecules on surface. The molecules of choice, fluorescein ( 1 ) and a new catechol derivative ( 2 ), exhibit several protonation states with distinct emission prop...

Description
Summary:Two different soft lithographic techniques (LCW and μCP) have been successfully used for the structuration of fluorescent pH-responsive molecules on surface. The molecules of choice, fluorescein ( 1 ) and a new catechol derivative ( 2 ), exhibit several protonation states with distinct emission properties over a large acid-base range. This allowed us to fabricate fluorescent arrays that respond over a large pH-window. Arrays of fluorescent pH-responsive multistate molecules show fluorescence sensing capabilities when they are exposed to atmospheres of different acidity over large pH-windows.
