α,β,γ,δ-四苯基卟啉,简称TPP,是卟吩环上α,β,γ,δ位上的氢被苯基取代后的产物。TPP是一种重要的人工合成卟啉化合物,它可用于太阳能贮存,同时又是合成金属卟啉化合物的中间体,它的过渡金属化合物可以做为烯烃的光氧化催化剂,而稀土金属卟啉化合物则被用作核磁共振位移试剂和生物大分子的探针。 α, β, γ, δ-tetraphenylporphyrin, or TPP for short, is the product of the substitution of phenyl with hydrogen in the α, β, γ, δ positions on the porphine ring. TPP is an important synthetic porphyrin compound which can be used for solar energy storage and is also an intermediate of synthetic metalloporphyrin compounds. Its transition metal compounds can be used as the photooxidation catalyst of olefins, while the rare earth metal porphyrin compounds It is used as a probe for NMR magnetic resonance shift reagents and biological macromolecules.
