Reversible temperature-responsible emission in solutions within 293-333 K produced by dissociative behavior of multinuclear Cu(I) complexes with aminomethylphosphines
A series of multinuclear Cu(I) complexes (CuI)(x)L-y, namely the previously reported (CuI)(6)L-2 and (CuI)(2)L’ and novel (CuI)(2)L-2, where L and L’ are 1,5-di(R)-3,7-bis(2-pyridine-2′-yl)ethyl-1,5-diaza-3,7-diphosphacyclooctanes are introduced. Both dissociative and oxidative behavior of the complexes in DMSO and DMF solutions are correlated with the time-dependent changes in their phosphorescence originated from (3)(X+ M)LCT transitions. The instability of butterfly-like (CuI)(2)L’ resulting in its oxidative degradation in DMSO and transformation into (CuI)L'(2) in DMF solutions differentiates it from more stable linear complexes (CuI)(6)L-2 and (CuI)(2)L-2. The complexes (CuI)(2)L-2 and (CuI)L-2 produced by the dissociation of (CuI)(6)L-2. in DMSO and DMF solutions are regarded as structural motifs responsible for both reversible blue-shifting by 10 nm of the emission band and the decrease in the excited states lifetime values upon the heating of the solutions within 293-333 K. This temperature-induced behavior along with the phosphorescence character of the emission of both complexes points to thermally activated delayed fluorescence as the reason for the reversible temperature-induced spectral changes of hexanuclear (CuI)(6)L-2. Smaller nuclearity of (CuI)(2)L-2 is the reason for partial reversibility of the spectral changes.
But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 6969-71-7, you can contact me at any time and look forward to more communication. COA of Formula: C6H5N3O.
