New lanthanide complex Gd-ANAMD containing 2-amino-7-methyl-1,8-naphthyridine was achieved for selective magnetic resonance imaging towards guanosine 5′-monophosphate over other ribonucleotide polyphosphates in aqueous media and in vivo. The formation of strong multi-hydrogen bonds between naphthyridine and guanosine made the phosphate in guanosine 5′-monophosphate positioned on a suitable site to...
A novel hybrid material (SBA-P1) is prepared through the functionalization of mesoporous silica (SBA-15) with a 1,8-naphthalimide-based dye by sol–gel reaction. The characterization results of elemental analysis (EA), X-ray powder diffractometer (XRD) and spectroscopic methods demonstrate the fluorescence dye P1 is successfully grafted onto the inner surface of SBA-15 and the organized structure is...
A new Rhodamine-based chemosensor RBSN designed for the selective detection of Hg 2+ in aqueous media is synthesized and structural characterized. It features brightness blue emission in the presence of Hg 2+ with the fluorescent detection limit for Hg 2+ in aqueous media being ppb levels and exhibits excellent Hg 2+ -specific luminescence enhancement over various competitive...
