Supramolecular polymerization of Pt(II) complex with terpyridine-based ligand possessing alanine moiety in nonpolar solvent

Cyclometalated Pt(II)‐Terpyridine Metallomesogen: What Is Visible or Invisible That Is a Matter of Molecular Packing and Orientation

“…For the PtM solution with 20 µm concentration, a high-energy absorption peak is observed between 250 and 350 nm, originated from π-π* intraligand charge transfer. [37][38][39] In addition, the low-energy absorption at 390 nm caused by dπ(Pt)-π*(tpy) metal-to-ligand charge transfer is discernible (Figure S7, Supporting Information). [39] The aggregation-induced photophysical properties of PtM in solution-state were studied by UV-vis experiment using 20 µm PtM in a cosolvent system of MC and diethyl ether (ether).…”

[39] The aggregation-induced photophysical properties of PtM in solution-state were studied by UV-vis experiment using 20 µm PtM in a cosolvent system of MC and diethyl ether (ether). In this system, PtM completely dissolves in MC as a good solvent and maintains a transparent state.…”

Platinum(ii) terpyridine-based supramolecular polymer gels with induced chirality

“…1, the solution of 1-Pt in DMSO was weak-emissive due to monomeric species with MLCT in a polar solvent. 30 However, the assembled 1-Pt exhibited a strong orange emission at 568 nm assigned as triplet metal–metal-to-ligand charge transfer ( 3 MMLCT) emission, originating from MMLCT with Pt–Pt interaction in a mixture of DMSO and H 2 O (v/v, 1/1) (Fig. 1).…”
