| description | Effectively regulating the rotary motions of molecular rotors through external stimuli poses a tremendous challenge. Herein, a new type of molecular rotor based on azobenzene-strapped mixed (phthalocyaninato)(porphyrinato) rare earth triple-decker complex <b>Azo-1</b> is reported. Electronic absorption and <sup>1</sup>H NMR spectra manifested the reversible isomerization of the rotor <b>Azo-1</b> between the <i>trans</i> configuration and the <i>cis</i> configuration. The rotational behavior of phthalocyanine rotator in two configurations were investigated by VT-<sup>1</sup>H NMR experiments, and the results indicated that the phthalocyanine rotator possessed a smaller rotational energy barrier in the <i>cis</i> isomer than in the <i>trans</i> isomer, which was also supported by DFT calculations. This result demonstrates that the rotation of phthalocyanine rotator in (phthalocyaninato)(porphyrinato) rare earth triple-decker complex can be successfully modulated by photo-isomerization via altering irradiation. |
