Visualizing biomolecules such as enzymes in the deep tissue of living organisms via molecular ratiometric fluorescent probes second near-infrared window (NIR-II) with a built-in self-calibration function can provide reliable information about relevant pathophysiological processes directly but so far is not feasible due to lack fluorescence modulation strategy NIR-II window. Here we present platform Py-2 by integrating rhodamine 6G scaffold and polymethine. The maximal emission wavelength was...

Despite having the potential to synthesize stable metal–organic frameworks (MOFs), rare earth metal-based MOFs have not been exploited extensively. Owing high coordination numbers, can generate a suitable environment for various applications. Herein, samarium (Sm)-based were synthesized with three different organic linkers, namely, trimesic acid (TMA), meso-tetra(4-carboxyphenyl)porphine (TCPP), and 1,3,6,8-tetra(4-carboxylphenyl) pyrene(TBPy) by solvothermal approach. The morphologies of...
