研究了以共价键连接卟啉—酞菁的双发色团分子内的能量传递过程。结果表明:在非极性溶剂中有利于能量传递,其效率可达70%,此类有机偶极分子的宏观三阶非线性极化率X~(3)=10~-10~(10)e.s.u.,酞菁衍生物亦具有作为光记录介质所需的优良性能。
The energy transfer process of double chromophore molecules with covalent bonding to porphyrin-phthalocyanine was studied. The results show that the energy transfer efficiency is up to 70% in apolar solvents. The third order nonlinear susceptibility of this kind of organic dipole molecules is X ~ (3) = 10 ~ -10 ~ (10) esu, phthalocyanine derivatives also have excellent properties as an optical recording medium.
