Design and Investigation of Optical Properties of N-(Rhodamine-B)-Lactam-Ethylenediamine (RhB-EDA) Fluorescent Probe.

This study presents chemical modification of a Rhodamine B (RhB) sensor probe by ethylenediamine (EDA), and investigation of its spectral as well as sensor properties to the various metals. The synthesised -(Rhodamine-B)-lactam-ethylenediamine (RhB-EDA) fluorescent probe shows interesting optical sensor properties, and high sensitivity and selectivity to Ag⁺ ions among all the tested metal ions (K⁺, Mg, Cu, Ni, Fe, Pb, Na⁺, Mn, Li⁺, Al, Co, Hg, Sr, Ca, Ag⁺, Cd and Zn), while the well-known Rhodamine B (RhB) fluorescent probe shows much less sensitivity to Ag⁺ ions, but high sensitivity to Fe ions. The novel fluorescent sensor probe RhB-EDA has the capabilities to sense Ag⁺ ions up to µM ranges by using the fluorescence quenching approach.

Application of PAMAM dendrimers in optical sensing.

The need for an improved sensor performance is always encouraging us towards exploring new materials. Following the invention of dendrimers, the possibility was recognised of using them for improving optical sensor performance. Their more important aspects are their two main structural properties: three-dimensional structure and multiple terminal functional groups.
