Resumo

Aiming the development of a nanothermometer, a new Type II metallopolymer consisting of a fluorene derivative polymer complexed with europium ions is introduced, as a material with good solubility in common organic solvents and easy film formation. The structural and photophysical properties are discussed focusing on the observed ratiometric thermochromism behavior in solid state. For comparison purposes, the same structure without the complexed ions (LaPPS75) and a model compound simulating the complexed sites (LaPPS75 M) were used. The ratiometric luminescent temperature shows an operational range between 260 and 380 K with a maximum relative thermal sensitivity of 3.29% K-1 at 380 K. (AU)
