  • 酞菁是一种重要的有机光电材料, 关于其晶体结构和光电性质间的内在关联尚存争议. 本文利用高压原位拉曼散射光谱及荧光光谱技术对酞菁晶体在高压下的结构转变和光学性质进行了研究. 当压力达到12.0 GPa时, 酞菁分子本身仍保持稳定, 没有发生开环反应. 酞菁晶体结构在压力作用下由α相逐渐转变为χ相, 这一转变在卸压后恢复到初始α相. 酞菁的高压荧光光谱研究表明, 荧光强度随压力增高而衰减, 至3.0 GPa时消失. 高压下酞菁分子间所形成的激基缔合物荧光受抑制, 而常压下α相酞菁中观察不到的酞菁分子荧光在高压下出现, 这可能与酞菁晶体中呈平行排列的分子之间在压力下重叠程度减小有关.
    Phthalocyanine (Pc) is a kind of important photoelectric material, but a lot of questions remain to be clarified, like the relationship between the structure of Pc and its photoelectric property. High pressure is a powerful tool to study the structure transformation. High pressure study on piezochromic materials, which shows color change under high pressure due to structure changing, serves as an effectively way of studying the relationship between materials’ structure and photoelectric property. In this work Raman spectrum is employed to study the phase change of α phase metal-free Pc (α-H2Pc) under high pressure, meanwhile the effect of pressure on fluorescence (FL) is also studied to show how the Pc’s structure affects the photoelectric property. The diamond anvil cell is employed to achieve the high pressure condition, by using NaCl as a pressure transmitting medium. And Raman and FL measurements are performed by using a LabRam HR Evolution spectrometer equipped with a 473 nm laser. The Raman spectra of α-H2Pc show to slightly change during compression to 12.0 GPa. The main Raman peaks remain at highest pressure, including the Raman peak from macrocyclic of Pc molecules, which shows the stability of Pc molecules. Note that an enhancement of Raman peak at 623 cm–1 can be found with the pressure increasing, which appears only in the Raman spectrum of χ phase metal-free Pc (χ-H2Pc), showing that α-H2Pc is converted into χ-H2Pc under pressure. The curve for Raman frequency as a function of pressure shows that no obvious evidence related to bonding or structure transition can be observed, which means that α-H2Pc is transformed into χ-H2Pc gradually. For FL spectrum, only the FL of excimer can be found in α-H2Pc at atmosphere pressure. When the solid α-H2Pc is compressed, the FL intensity is found to decrease as pressure increases, and it is quenched at 3.0 GPa. The FL of Pc molecule, which is not found in α-H2Pc at ambient pressure, appears at 0.7 GPa. As the pressure increases, the FL intensity ratio between Pc molecule and excimer is enhanced. Considering the pressure induced phase transition from α-H2Pc to χ-H2Pc gradually, the change in FL spectrum should be due to the structure transformation. It is proved that the degree of overlapping between Pc molecules in α-H2Pc is larger than that in χ-H2Pc. We think, the degree of overlapping decreases under high pressure, which hinders the formation of excimer. It makes the excimer emission decrease and the FL of Pc molecules appear under high pressure. Our work can explain the relationship between Pc crystal structure and its fluorescence, reveals the kinetic behavior of macromolecules similar to Pc system under high pressure, and provides a new possibility of designing the photoelectric materials with excellent performances.
