Fig. 3. (a, b) UV-vis absorption spectra of the mixture of HITCI with (a) RhB-C2 and (b) RhB-C18 after photoirradiation. (c) Time-course of absorbance at 735 nm after photoirradiation using RhB-C2 (black circle) and RhB-C18 (red circle). (d) Linear regression plots of HITCT absorbance with RhB-C2 (black circle) and RhB-C18 (red circle). Experimental conditions: [RhB-C2] = [RhB-C18] = 5.0 μM, [HITCI] = 2.5 μM solvent: water, rt, irradiation wavelength: 560 nm (FWHM: 10 nm, Xe lamp, 300 W).
