4-Amino-/V-

All these features were observed experimentally for solutions of 3-amino-/V-methylphthalimide, 4-amino-/V-methylphthalimide, and for nonsubstituted rhoda-mine. The results were observed for cooled, polar solutions of phthalimides, in which the orientational relaxation is delayed. Exactly the same spectral behavior was observed [50] by picosecond spectroscopy for low viscosity liquid solutions at room temperature, in which the orientational relaxation rate is much higher. All experimental data indicate that correlation functions of spectral shifts Av-l(t), which are used frequently for describing the Time Dependent Stokes Shift, are essentially the functions of excitation frequency.

Solvatochromic fluorescent probe molecules have also been used to establish solvent polarity scales. The solvent-dependent fluorescence maximum of 4-amino-V-methylphthalimide was used by Zelinskii et al. to establish a universal scale for the effect of solvents on the electronic spectra of organic compounds [80, 213], More recently, a comprehensive Py scale of solvent polarity including 95 solvents has been proposed by Winnik et al. [222]. This is based on the relative band intensities of the vibronic bands I and III of the % - n emission spectrum of monomeric pyrene cf. Section 6.2.4. A significant enhancement is observed in the 0 0 vibronic band intensity h relative to the 0 2 vibronic band intensity /m with increasing solvent polarity. The ratio of emission intensities for bands I and III serves as an empirical measure of solvent polarity Py = /i/Zm [222]. However, there seems to be some difficulty in determining precise Py values, as shown by the varying Py values from different laboratories the reasons for these deviations have been investigated [223].

Amino-V-methylphthalimide was treated with sodium hydride and then reacted with penta(ethylene glycol) ditosylate to afford a crowned phthalimide 3. In this reaction, an a,(0-bichromophoric podand 4 was also obtained. Subsequent reaction of the phthalimide 3 with hydrazine provided the desired crowned isoluminol 1,... 

Phthalimides and Related Compounds - 4-Amino-./V-methylphthalimide has been studied by laser flash photolysis. The photophysical parameters have been established by this approach and this study has supported the results obtained from steady state irradiations. Intramolecular photoelectron transfer photochemistry of the A-[(JV-acetyl-./V-trimethylsilyl-methyI)amidoalkyl]phthali-mides has been demonstrated. The yields obtained on irradiation in methanol range from low to medium.
