... which influences the flu- orescence intensity. Therefore, the influence of the vol- ume of buffer was measured. Because the volume of buffer added (1.00–3.00 mL) had little effect on the fluorescence ... fluorophores. The compound could be dis- solved in aqueous solution and showed high binding ability because of the two adjacent bis(b-CD)s. Because of the conformation o...
