“…The Mott–Seitz model (eq ) can be used for various cases of dual center emission, e.g. , Tb 3+ /Eu 3+ , lanthanide ions combined with a QD, Tb 3+ /Tm 3+ , Yb 3+ /Nd 3+ , and other systems. − These systems show an S-shaped curve for Δ( T ), which deviates from an exponential intensity profile (especially above 200 K). Equation is a modified version of the Mott–Seitz model, which can be employed when one of the transitions exhibits a temperature dependence much smaller than the other (here, the temperature dependence of FL is much lower than RhB).…”

Macro-and nanosized core, as well as core−shell, γcyclodextrin metal−organic frameworks (γ-CD-MOFs) have been designed and used as platforms for the encapsulation of dye molecules to develop the first CD-MOF-based ratiometric optical thermometer materials. A novel dye combination was employed for this purpose, i.e., the duo rhodamine B (RhB) and fluorescein (FL). RhB is highly temperature-sensitive, whereas FL is less temperature-sensitive, and its luminescence emission peak is used as a reference. Promising results in terms of thermometric properties were obtained for a series of dye-encapsulated γ-CD-MOF materials based on this dye combination, with high relative sensitivities, even up to 5%K −1 , for the dye-encapsulated 75%RhB-25%FL nanosized γ-CD-MOF, among the highest performance values reported so far for luminescent dual thermometers. In our study, we have additionally developed a simple yet effective preparation method for core−shell γ-CD-MOFs, allowing effective manipulation of the γ-CD-MOF shell growth. The proposed method allows incorporation of the FL and RhB dyes in the γ-CD-MOFs in a more controlled manner, enhancing the efficiency of the developed ratiometric (macro) γ-CD-MOF thermometers.

“…Three of the most studied approaches to designing a fluorescent nanothermometer are changes in emission intensity, − ratiometric fluorescence, − and changes in lifetime. , Each method has its advantages and disadvantages including photobleaching, sensitivity to pH , or ionic strength, and concentration dependence. Using changes in emission intensity allows for rapid measurements, but each experiment must be calibrated with a baseline and is greatly affected by photobleaching and the concentration of probe in each cell. ,,, The ratiometric approach self-calibrates and also allows for quick measurement; however, these are often polymers that are also affected by pH and ionic strength and have large dimensions ,,, which could affect their internalization, diffusion, and function in cells.…”

Boron dipyrromethene (BODIPY) molecular rotors have shown sensitivity toward viscosity, polarity, and temperature. Here, we report a 1,3,5,7-tetramethyl-8-phenyl-BODIPY modified with a polyethylene glycol (PEG) chain, for temperature sensing and live cell imaging. This new PEG-BODIPY dye presents an increase in nonradiative decay as temperature increases, which directly influences its lifetime. This change in lifetime is dependent on changes in both temperature and viscosity at low viscosity values, but is only dependent on temperature at high viscosity values. The dependence of fluorescence lifetime with temperature allows for temperature monitoring in vitro and in cells, with sub degree resolution. When in contact with cells, the PEG-BODIPY spontaneously penetrates and stains the cell but not the nucleus. Furthermore, no significant cell toxicity was found even at 100 μM concentration. Using fluorescence lifetime imaging microscopy (FLIM), we were able to observe the changes in the lifetime of PEG-BODIPY within the cell at different temperatures. The use of FLIM and molecular probes such as PEG-BODIPY can provide important information about cellular temperature and heat dissipation upon medically relevant stimuli, such as radiofrequency ablation and photodynamic therapy.

“…The first and most common method is based on changes in emission intensity [ 2 , 3 , 4 , 5 , 6 ]. The second method to measure temperature is based on the ratiometric fluorescence of a molecular probe [ 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 ]. The third approach involves changes in the lifetime of the probe [ 17 , 18 ].…”

We developed a fluorescent molecular probe based on gold nanoparticles functionalized with N,N′-bis(2-(1-piperazino)ethyl)-3,4,9,10-perylenetetracarboxylic acid diimide dihydrochloride, and these probes exhibit potential for applications in microscopic thermometry. The intensity of fluorescence was affected by changes in temperature. Chemical environments, such as different buffers with the same pH, also resulted in different fluorescence intensities. Due to the fluorescence intensity changes exhibited by modified gold nanoparticles, these materials are promising candidates for future technologies involving microscopic temperature measurements.
