Absorption and Emission Properties of 7 b and 8 b in the Presence of ct DNA, 22AG and PSS.

	λ abs [a]	log ϵ [b]	Δλ abs [c]			λ fl [d]	Δλ fl [e]
			ct DNA	22AG	PSS		ct DNA	22AG	PSS
7 b	528	4.60	3	0	7	–[f]	–[f]	–[f]	–[f]
8 b	576	4.61	9	12	13	671	−21	−21	−22

[a] Long‐wavelength absorption maximum (in nm); c=5–10 μm in phosphate buffer (pH 7.0; with 2.5–5 % v/v DMSO). [b] Molar extinction coefficient. [c] Shift of the long‐wavelength absorption maximum between free and bound ligand (in nm). [d] Long‐wavelength emission maximum (in nm); c=5–10 μm in phosphate buffer (with 2.5–5 % v/v DMSO), λ _ex=515 nm. [e] Shift of the long‐wavelength emission maximum between free and bound ligand (in nm). [f] Not determined.
