| Abstract: | A series of cholesterol‐/estradiol‐appended alkynylplatinum(II) complexes with tridentate N‐donor ligands, based on 2,6‐bis(1‐alkylpyrazol‐3‐yl)pyridine, has been synthesized and characterized by 1H NMR spectroscopy, FAB‐mass spectrometry, and elemental analysis. Their photophysical properties have also been investigated. Computational studies have been performed to provide insights into the nature of the electronic transitions. Some of the complexes have been found to form stable thermo‐ and mechanoresponsive supramolecular gels. |
