A new rhodamine-based fluorescent chemosensor for transition metal cations synthesized by one-step facile condensation
TL;DR: In this article, a new rhodamine-based fluorescent chemosensor for transition metal cations was synthesized by one-step facile condensation of Rhodamine B and 2-aminopyridine.
Journal ArticleDOI
Rhodamine-aminopyridine based fluorescent sensors for Fe3+ in water: Synthesis, quantum chemical interpretation and living cell application
TL;DR: In this paper, three compounds of rhodamine-triazine aminopyridine derivatives (sensor RC2P-RC4P) were synthesized and a simple paper test strip was developed for the rapid monitoring of Fe3+ in living HL-7702 cells.
Journal ArticleDOI
Mechanism for different fluorescence response of a coumarin-amide-dipicolylamine linkage to Zn(II) and Cd(II) in water.
TL;DR: A coumarin-amide-dipicolylamine linkage was synthesized and used as a fluorescent receptor for metal cations in water and revealed that the structure difference for Zn and Cd complexes results in longer- and shorter-wavelength fluorescence.
Journal ArticleDOI
Chelating C4-bound imidazolylidene complexes through oxidative addition of imidazolium salts to palladium(0)
TL;DR: In this paper, the activation of the C4 position does not necessitate protection of the imidazolium C2 position, thereby leaving this site available for further modification.

Density‐functional thermochemistry. III. The role of exact exchange
TL;DR: In this article, a semi-empirical exchange correlation functional with local spin density, gradient, and exact exchange terms was proposed. But this functional performed significantly better than previous functionals with gradient corrections only, and fits experimental atomization energies with an impressively small average absolute deviation of 2.4 kcal/mol.
Journal ArticleDOI
Development of the Colle-Salvetti correlation-energy formula into a functional of the electron density
TL;DR: Numerical calculations on a number of atoms, positive ions, and molecules, of both open- and closed-shell type, show that density-functional formulas for the correlation energy and correlation potential give correlation energies within a few percent.
