The optical response of a solvatochromic dye, [(E)-3-(1-methyl-1H-indol-3-yl)-1-phenylprop-2-en-1-one], N1, has been studied in the AOT/n-heptane/water reverse micellar media using steady-state and time-resolved techniques. To this end variation in the photophysical properties of N1 have been systematically studied as a function of water pool size (w₀). Micropolarity, microviscosity, and relative permittivity of the immediate microenvironment surrounding the probe has been estimated from the limiting values of the photophysical parameters of N1 at high w₀. Information about the location of the dye in the reverse micellar media has been obtained using the observed results.
