摘要：

The synthesis of 2,3,5,7,8,10,12,13,15,17,18,20-dodecaphenylporphyrin (DPP ; 3) is reported; compared with similar porphyrins it shows a red. shifted electronic absorption spectrum, indicating a non-planar conformation in solution. Variable temperature 500 MHz NMR experiments give a ΔG* of 10.9 kcal mol-1 at 253 K for inversion of the macrocycle. © 1990.
