Abstract:
This paper reports the thermodynamics of reversible oxygen binding to a dicobalt di(meso-tetraphenylporphyrin) linked by a diamido- aliphatic chain in N,N-dimethylformamide solution. Thermodynamic values(standard state 101325 Pa O_2): △G ~θ(298 K)=-3.1 kJ·mol~(-1), △H~θ (298 K)=-37.1 kJ·mol~(-1), △S~θ (298 K)=-114 J·mol~(-1)·K~(-1), Co:O_2=1:1. The ESR parameters of the dioxygen complex in DMF at 133 K are as follows: g_⊥=2.000, g_(||)=2.046, A~(C_0)_⊥=15G, A~(C_0)_(||)=22G, The pressure of dioxygen necessary for half-oxygenation of the system (P_(1/2)=42.7 kPa at 288 K) is comparable with that for cobalt substituted human hemoglobin at T state.
