Chemically Converted Graphene Induced Molecular Flattening of 5,10,15,20-Tetrakis(1-methyl-4-pyridinio)porphyrin and Its Application for Optical Detection of Cadmium(II) Ions
Abstract
Complexation of cationic 5,10,15,20-tetrakis(1-methyl-4-pyridinio)porphyrin (TMPyP) and negatively charged chemically converted graphene (CCG) sheets was performed by simply mixing the diluted aqueous solutions of both components. During this process, a large bathochromic shift of porphyrin Soret band from 421 to 458 nm was observed, which is attributed to the flattening of TMPyP molecules induced by CCG through electrostatic and pi-pi stacking cooperative interactions. Furthermore, the coordination reaction between TMPyP and Cd(2+) ions was greatly accelerated from 20 h to 8 min under ambient conditions by introducing CCG sheets. On the basis of this phenomenon, we used the complex of TMPyP and CCG as an optical probe for rapid and selective detection of Cd(2+) ions in aqueous media.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
