Sensors using fluorescent with high sensitivity and selectivity are attracting attention in variety of research directions. The understanding of structure photophysical relationship of a given fluorophore and development of supramolecular chemistry has enabled the discovery of several useful fluorescent sensors through the integration of chelators or functional moiety at specific position. Here we present a fluorescent sensor array for pH sensing system. Based on pKa value of the functional group, we designed 30 different fluorescent compounds responding with the pH changes via incorporation of pH sensitive functional groups on C-1 position of Kaleidolizine. Simple spotting of the fluorescent compounds on cellulose filter paper printed with wax allowed us to generate a single array. By analyzing fluorescence pattern changes of the array, we successfully monitored the pH differences of the samples.
