Plate-like CDots/EuBDC nanocomposite for ratiometric luminescence thermometry

Abstract

The synthesis of dual-emission nanocomposite materials has emerged as an excellent strategy for designing new and advanced luminescent ratiometric thermometers.

Bicomponent Fluorescent System Composed of Peptide-Substituted Naphthalenediimide and Carbon Dots as Nanothermometer

“…23,24 In comparison to the single-component analogue, two-component systems may provide an opportunity to develop an efficient nanothermometer as there is a possibility of intermolecular interaction to form a dual emissive two-component system to tune the fluorescence color or peak positions of the system upon variation of temperature. 25,26 The dual emissive twocomponent system can be achieved upon the formation of covalent or noncovalent conjugation between the components. 18,26 C-dots are metal-free carbon-based nanomaterials that are highly emissive with good quantum yield and display stimuliresponsive emission ranging from blue to red.…”

“…In this context, highly fluorescent carbon dots , and core-substituted naphthalenediimide-based organic dyes − are good choices in designing fluorescent nanothermometers. There are many reports of single-component fluorescence nanothermometers that generally exhibit efficiency due to a change in the fluorescence intensity rather than a change in emission wavelength. , In comparison to the single-component analogue, two-component systems may provide an opportunity to develop an efficient nanothermometer as there is a possibility of intermolecular interaction to form a dual emissive two-component system to tune the fluorescence color or peak positions of the system upon variation of temperature. , The dual emissive two-component system can be achieved upon the formation of covalent or noncovalent conjugation between the components. , …”

“…photostability, and biocompatibility make them more attractive in drug delivery, bioimaging, photocatalysis, and others.29−40 C-dots become a good replacement for other metal-based nanomaterials due to their low toxicity, easy synthesis, and cheap production cost. Recently, to improve the efficiency of only the C-dots-based nanothermometer, the C-dots have been covalently or noncovalently functionalized with the organic molecule to get a dual emissive nanothermometer.10,18,26 Naphthalene dianhydride (NDA) is one of the important πconjugated organic molecules among the rylene dyes 41. The endowed physical properties including molecular planarity, air stability, chemical robustness, and high π-acidity make NDA a promising candidate in diverse research fields like organic lightemitting diodes (OLED), photovoltaic devices, solar cells, field effect transistors, bioprobes, and others.42−48 Functionalization with the peptides at the periphery of NDA leads to the formation of peptide-appended imide and core-substituted naphthalenediimides (NDIs and c-NDIs).49−52 The incorporation of a peptide may facilitate tuning of the self-assembling property of NDIs using the H-bonding interactions of the CO-NH group of the peptide.53−56 Depending on the electrondonating capability of a functional group at the core position of NDIs, a rainbow collection of fluorescent c-NDI can be obtained 57.…”
