Red-light-absorbing diimine Pt(II) bisacetylide complexes showing near-IR phosphorescence and long-lived 3IL excited state of Bodipy for application in triplet-triplet annihilation upconversion.

چکیده
Bodipy is used for the preparation of Pt(II) bisacetylide complexes which show strong absorption of visible light and long-lived triplet state. Room temperature (RT) near-IR phosphorescence of Bodipy was observed. The π-conjugation framework of visible light-harvesting Bodipy ligand was connected to the Pt(II) center by the C≡C bond. The complexes were used as triplet photosensitizers for triplet-triplet annihilation (TTA) upconversion.

Accessing the long-lived near-IR-emissive triplet excited state in naphthalenediimide with light-harvesting diimine platinum(II) bisacetylide complex and its application for upconversion.
Room temperature near-IR phosphorescence of naphthalenediimide (NDI) was observed with N^N Pt(II) bisacetylide complex (Pt-NDI) in which the NDI was connected to Pt(II) center via acetylide. Pt-NDI shows intense absorption of visible light and long-lived NDI-localized excited state ((3)IL) (τ(T) = 22.3 μs). Pt-NDI was used as a triplet sensitizer for upconversion.

A rhodamine moiety was used for the preparation of trans bis(tributylphosphine) Pt(II) bisacetylide complexes (RH-BDPY-Pt-1 and RH-BDPY-Pt-2, with two different Bodipy acetylide ligands), which show acid/base-switchable photophysical properties. The rhodamine moiety undergoes reversible spirolactam ↔ opened amide structure transformation in the presence of an acid/base. Bodipy ligands are respo...

Two N^N Pt(II) bis(acetylide) complexes Pt-1 and Pt-2 with regioisomeric amino NI acetylide ligands (L-1 and L-2, L-1 = 5-amino-4-ethylnaphthaleneimide; L-2 = 3-amino-4-ethylnaphthaleneimide) were prepared. The photophysical properties of the complexes were studied by steady state and time-resolved spectroscopy. The two complexes with regioisomeric ligands (Pt-1 and Pt-2) show different photoph...

A dbbpy platinum(II) bis(coumarin acetylide) complex (Pt-1, dbbpy = 4,4'-di-tert-butyl-2,2'-bipyridine) was prepared. Pt-1 shows intense absorption in the visible region (λ(abs) = 412 nm, ε = 3.23 × 10(4) M(-1) cm(-1)) compared to the model complex dbbpy Pt(II) bis(phenylacetylide) (Pt-2, λ(abs) = 424 nm, ε = 8.8 × 10(3) M(-1) cm(-1)). Room temperature phosphorescence was observed for Pt-1 ((3)...

We report on five new complexes with the general formula trans-Pt(BODIPY)X(PEt3)2 (), where the platinum(ii) ion is σ-bonded to a 4,4-difluoro-4-bora-3a,4a-diaza-s-indacen-8-yl (BODIPY) and an anionic ligand X(-) (X(-) = Cl(-), I(-), NO2(-), NCS(-), CH3(-)). All five complexes were characterized by multinuclear NMR, electronic absorption and luminescence spectroscopy and by X-ray diffraction an...
