Photophysical investigation of highly phosphorescent N^C^N platinum(II) azido complexes and their triazole derivatives / F. Fagnani, G. De Soricellis, A. Colombo, C. Dragonetti, D. Roberto, A. di Biase, S. Fantacci, D. Marinotto. - In: DYES AND PIGMENTS. - ISSN 0143-7208. - 225:(2024), pp. 112064.1-112064.8. [10.1016/j.dyepig.2024.112064]
Abstract:
Substitution of chloride by azide in cyclometalated 5-R-1,3-di(2-pyridyl)-benzene platinum(II) complexes (R =
mesityl, methyl or 2-thienyl) leads to novel azido complexes with an intense phosphorescence that is modulated
by the nature of R. An increase of the concentration brings about to the formation of aggregates with a red-shifted
emission. Furthermore, the presence of the ancillary azido group allows, via i-click reaction, the obtainment of
even more emissive 1,2,3-triazole derivatives. The 1,2,3-triazolate of the mesityl and 2-thienyl N^C^N–Pt(II)
complexes were characterized by X-ray diffraction analysis and their photophysical properties were deeply
investigated.
