Solvent effect on the photophysical properties of 4-phenoxy-N-methyl-1,8-naphthalimide

Autor: Francisco Carlos Nart, P. Berci Filho, Eduardo Rezende Triboni, Marcelo Henrique Gehlen, Janildo Lopes Magalhães, Robson Valentim Pereira

Publikováno v: Journal of Photochemistry and Photobiology A: Chemistry. 183:165-170

The photophysical properties of N-methyl-1,8-naphthalimide (NI) and 4-phenoxy-N-methyl-1,8-naphthalimide (4-PNI) are studied by steady-state and time-resolved emission measurements. Both absorption and fluorescence spectra are red-shifted when the el

Rate-limiting step and micellar catalysis of the non-classical nitro group nucleophilic substitution by thiols in 4-nitro-N-n-butyl-1,8-naphthalimide

Autor: Iolanda M. Cuccovia, Hernan Chaimovich, Mário José Politi, P. Berci Filho, Eduardo Rezende Triboni

Publikováno v: Journal of Physical Organic Chemistry. 16:311-317

Nitronaphthalimides are a particularly interesting group of nitroaromatics used for staining cells in hypoxia and in photodynamic therapy. The kinetics of the aromatic nucleophilic substitution of the nitro-group of 4-nitro-N-n-butyl-1,8-naphthalimid

Photophysical properties of N-alkylnaphthalimides and analogs

Autor: G.R. Molinari, Mário José Politi, Vicente G. Toscano, P. Berci Filho, T.C. Barros

Publikováno v: Journal of Photochemistry and Photobiology A: Chemistry. 76:55-60

Photophysical studies of 1.8 ( I ) and 2.3 ( II ) N-butylnaphthalimides were realized. UV/Vis absorption and fluorescence properties for I and II as a function of solvent polarity and proticity show a higher π orbital interaction between the imide a
