Highly selective and sensitive phosphane sulfide derivative for the detection of Hg2+ in an organoaqueous medium.
A new fluorescent molecular sensor for Hg2+ based on the phosphane sulfide derivative exhibits a very low detection limit in an aqueous medium (3.8 nM) with a very high selectivity over otherExpand

Synthesis, fluorescence, and two-photon absorption of bidentate phosphane oxide derivatives: complexation with pb(2+) and cd(2+) cations.
A series of fluorescent phosphane oxide derivatives based on diphenylphosphanoethane (DPPE) and diphenylphosphanomethane (DPPM) skeletons has been prepared by means of Grignard reactions andExpand

Synthesis of novel rod-shaped and star-shaped fluorescent phosphane oxides--nonlinear optical properties and photophysical properties.
The design of a new class of fluorophores is presented. Some push-pull chromophores (D-pi-A) containing polyphenylethynyl units and a phosphane oxide moiety were efficiently prepared from commonExpand

First observation in the gas phase of the ultrafast electronic relaxation pathways of the S(2) states of heme and hemin.
The time evolution of electronically excited heme (iron II protoporphyrin IX, [Fe(II) PP]) and its associated salt hemin (iron III protoporphyrin IX chloride, [Fe(III) PP-Cl]), has been investigatedExpand

An efficient indirect mechanism for the ultrafast intersystem crossing in copper porphyrins.
The ultrafast dynamics of copper tetraphenylporphyrin (CuTPP), copper octaethylporphyrin (CuOEP), and of the free base tetraphenylporphyrin (H2TPP), excited in the S2 state have been investigated inExpand
