Das, Sujoy; Rissanen, Kari; Sahoo, Prithidipa published the artcile< Rare Crystal Structure of Open Spirolactam Ring along with the Closed-Ring Form of a Rhodamine Derivative: Sensing of Cu2+ Ions from Spinach>, Name: 2-(2-Aminoethyl)-3′,6′-bis(diethylamino)spiro[isoindoline-1,9′-xanthen]-3-one, the main research area is crystal structure spirolactam ring copper ion spinach.
Crystal structures of a rhodamine derivative in its closed and open spirolactam ring form combined with a selective and sensitive detection of Cu2+ ion at micromolar range in neutral medium. The chemosensing properties of the probe through a pentacoordinate Cu2+ ion were proven by spectroscopic and theor. anal. The spirolactam ring opening as the Cu2+ selective sensor was applied to spinach (Spinacia oleracea) to estimate the accumulation of copper as copper(II) into the plant.
