Bright fluorescence through activation of a low absorption fluorophore: The case of a unique naphthalimide-tetrazine dyad
Qing, Zhou,Audebert, Pierre,Clavier, Gilles,Meallet-Renault, Rachel,Miomandre, Fabien,Tang, Jie
, p. 1678 - 1682 (2011)
An original fluorescent dyad has been prepared, featuring a 1,8-naphthalimide chromophore linked to a fluorescent tetrazine. This bichromophore benefits from the good absorption coefficient of the imide, and displays a quasi complete energy transfer to the tetrazine, followed by its fluorescence emission. This allows the preparation of remarkable transparent solutions and solids displaying a strong yellow fluorescence with a long life-time.
Naphthalimide-based fluorescent Zn2+ chemosensors showing PET effect according to their linker length in water

We have developed naphthalimide-based fluorescent chemosensors that exhibit fluorescence enhancement upon binding Zn2+ ion in 10 mM HEPES buffer (pH 7.4) at 25 °C. The fluorescence enhancement was induced by a PET inhibition process in which electron transfer from the nitrogen lone pair electrons of the Dpa unit to naphthalimide was blocked upon the binding of the sensor to Zn2+. The longer the linker length (n = 1-3) of the sensor, the less the PET efficiency becomes. Among the sensors (1, 2, and 3) examined, 1 shows the highest selectivity and sensitivity for Zn2+ over other transition metal ions and alkali metal ions in water.

Rogers, Joy E.,Weiss, Sharon J.,Kelly, Lisa A.
, p. 427 - 436 (2000)
Despite the growing number of redox-active chromophores utilized to photoinduce oligonucleotide cleavage, detailed correlations between the degree of ground-state complexation and product yields have not been developed. To elucidate the specific role of s

N-(2-hydroxyethyl)-, N-(2-methoxyethyl)-, N-(3-hydroxypropyl)-, and N-(3-methoxypropyl)-1, 8- naphthalimide (1, 2a, 2b, 3a, and 3b, respectively) were prepared and their photophysical properties examined. The UV and IR spectra of 2a and 3a indichloromethane showed the presence ofintramolecular hydrogen bonding between the carbonyl group and the hydroxy group. In addition, the fluorescence intensities of 2a and 3a indichloromethane were found to be about two times larger than those of 1, 2b, and 3b. Furthermore, the fluorescence lifetimes of 2a and 3a, determined by picosecond single photon counting, were about two times longer than those of 1, 2b, and 3b. The rate constants of the intersystem crossing (kisca nd 3a, calculated based on the quantum yields of the intersystem crossing (Pisc) determined by the time-resolved thermallensing technique, were about one half of those obtained for 1, 2b, and 3b, while the rate constants of fluorescence emission (k f) and internal conversion (kic) were minimally affected by the presence of intramolecular hydrogen bonding. Enhancement of the fluorescence quantum yield and the lifetime of 2a and 3a was thus explained by a decrease in the efficiency of the intersystem crossing from 1(ππ*)to 3(nπ*), that results from an increase in the energy of the 3(nπ*) level due to the presence of intramolecular hydrogen bonding.
