on the platinumcomplexes trans-Pt(BODIPY)(8-ethynyl-BODIPY)(PEt3)2 (EtBPtB) and trans-Pt(BODIPY)(4-ethynyl-1,8-naphthalimide)(PR3)2 (R = Et, EtNIPtB-1; R = Ph, EtNIPtB-2), which all contain two different dye ligands that are connected to the platinum atom by a direct σ bond. The molecular structures of all complexes were established by X-ray crystallography and show that the different dye ligands
我们报告了铂络合物反-Pt(BODIPY)(8-乙炔基-BODIPY)(PEt 3)2(EtBPtB)和反-Pt(BODIPY)(4-乙炔基-1,8-萘二甲酰亚胺)(PR 3)2(R = Et,EtNIPtB-1 ; R = Ph,EtNIPtB-2),它们都包含两个不同的染料配体,它们通过直接的σ键连接到铂原子上。所有配合物的分子结构均通过X射线晶体学确定,表明不同的染料配体处于共面或正交排列。π堆积以及在膦取代基上涉及质子的多个CH···F和短CH···π相互作用导致晶体中有趣的堆积图案。配合物具有多种强吸收(ε= 3.2×10 5 –5.5×10 5 M –1 cm –1),涵盖从350到480 nm(EtNIPtB-1和EtNIPtB-2)或从350到580 nm(EtNIPtB-1)的范围。EtBPtB)。除了两种附着染料的典型吸收带外,它们还具有400-420 nm附近的强带,

Substitution of F-Bodipy with alkynylaryl residues at boron, at the pyrrolic core or at the meso position, provides unique tri-, tetra-, and pentasubstituted dyes. Substitution at the (pyrrolic) 2,6-positions provides substantial red shifts with quantum yields in the 40-90% range and excited-state lifetimes of 3-7 ns. ON/OFF fluorescence switching can be produced by protonation of dibutylamino subunits.
