Synthesis and Photophysical Properties of Star‐Shaped Triphenylamine Trimers Functionalized With BODIPY and Subphthalocyanine Chromophores

open access: yesChemistry – A European Journal, EarlyView.
This study investigates how molecular topology influences the photophysical properties of star‐shaped, threefold‐symmetric triphenylamine (TPA) derivatives functionalized with three BODIPY or SubPc units. Their absorption spectra exhibit minimal solvatochromism, whereas their fluorescence intensity is strongly dependent on solvent polarity.
