Temperature Tunable Optical Properties of Tetraheptylaluminum(III) Porphyrin Toward Molecular Thermometer

ChemPhysChem, EarlyView.
An amphiphilic aluminum(III) porphyrin (AlC7P) has been developed, and its temperature‐dependant aggregation‐induced photophysical properties have been investigated. The observed photophysical changes due to the aggregation in haxanes make AlC7P a suitable candidate for a luminescent molecular thermometer.
