The synthesis and mercury-recognizing skill of two emission "turn-on" rhodamine derivatives excited by rare earth up-conversion lattice

The present paper focused on the synthesis and Hg(II)-sensing behavior of two rhodamine derived probes. Up-conversion NaYF4 nanocrystals were constructed and applied as the excitation host so that those probes could be lightened by the 980 nm e

New fluorescent probe based on rhodamine derivative for detection of both Cu2+ and L-Methionine and living cells imaging

This paper developed a new fluorescent rhodamine-based derivatives (RAD) probe for highly sensitive and selective detection of Cu2+ and L-Methionine (L-Met). The detection limits can reach as low as 12 nM for Cu2+ and 5 nM for L-Met, In addition, the RAD probe can be further applied to cell imaging owing to its photostability and low cytotoxicity.

Reversible photochromic system based on rhodamine B salicylaldehyde hydrazone metal complex

Photochromic molecules are widely applied in chemistry, physics, biology, and materials science. Although a few photochromic systems have been developed before, their applications are still limited by complicated synthesis, low fatigue resistance, or incomplete light conversion. Rhodamine is a class of dyes with excellent optical properties including long-wavelength absorption, large absorption coefficient, and high photostability in its ring-open form. It is an ideal chromophore for the development of new photochromic systems. However, known photochromic rhodamine derivatives, such as amides, exhibit only millisecond lifetimes in their colored ring-open forms, making their application very limited and difficult. In this work, rhodamine B salicylaldehyde hydrazone metal complex was found to undergo intramolecular ring-open reactions upon UV irradiation, which led to a distinct color and fluorescence change both in solution and in solid matrix. The complex showed good fatigue resistance for the reversible photochromism and long lifetime for the ring-open state. Interestingly, the thermal bleaching rate was tunable by using different metal ions, temperatures, solvents, and chemical substitutions. It was proposed that UV light promoted isomerization of the rhodamine B derivative from enol-form to keto-form, which induced ring-opening of the rhodamine spirolactam in the complex to generate color. The photochromic system was successfully applied for photoprinting and UV strength measurement in the solid state. As compared to other reported photochromic molecules, the system in this study has its advantages of facile synthesis and tunable thermal bleaching rate, and also provides new insights into the development of photochromic materials based on metal complex and spirolactam-containing dyes.
