UV/vis spectra of TPPC@PAMAM in aqueous solution at different concentrations. [TPPC@PAMAM] = 3M (solid line), [TPPC@PAMAM] = 3mM (dashed line, spectrum made using 0.001 cm path length quartz cell) in phosphate buffer 1mM pH 7, T = 298 K. Figure S2. UV/vis spectra of TPPC@PAMAM and relative deconvolution. 2 Figure S3. Absorbance of 410 nm (empty circle) and 422nm (fully circle) deconvoluted species at different [PAMAM] / [TPPC] stoichiometric ratios. Figure S4. Fluorescence decays of TPPC@PAMAM in aqueous solution at 298 K, together with the fit curves (the straight lines) and the weighted residuals. 3 Figure S5. Anisotropy decays for TPPC sodium salt in aqueous solution, the curve fit (straight line) is plotted. Figure S6. Anisotropy decays for TPPC sodium salt in DMSO/water 1/1 mixture solvents and urea 6M, the curve fit (straight line) is plotted. 4 Figure S7. Anisotropy decays for TPPC@PAMAM (1/1) in aqueous solution, the curve fit (straight line) is plotted. Figure S8. Anisotropy decays for TPPC@PAMAM (1/50) in aqueous solution, the curve fit (straight line) is plotted. 5 Figure S9. UV/Vis spectra of DNA in presence of TPPC@PAMAM at various r = [TPPC@PAMAM] / [DNA] (base pairs) values. [DNA] = 50 M, r = 0 – 2.2, phosphate buffer 1 mM pH 7, [NaCl] = 10 mM , T = 298 K. Figure S10. Anisotropy decay for TPPC@PAMAM in a 1/1 ratio in the presence of DNA in aqueous solution; the curve fit (straight line) is plotted. 6
