英文摘要： The conjugated oligomer is the research object in this project. We analyze the influence and rule of photoluminescence and energy transfer of oligomers manipuled by photonic crystal structure, through measuring the steady and transient dynamic spectroscopy of oligomers in three types of situation, such as solution, solid and photonic crystal, and theoretically calculating the photonic stop band, transmittance spectrum, density of state and continuous rate distribution function. So this specifical contents could be summarized in three aspects: (1) Preparing and characterizing the nanostructure of opal and inverse opal photonic crystals. (2) Investigating the rules and mechanism of oligomer's photoluminescence manipulated by photonic crystals (3) Investigating rules and mechanism of photoluminescence and energy transfer process between dimer manipulated by photonic crystals. Through theoretical and experimental investigating the monomer and dimer,we will reveal the rules and mechanism of photoluminescence and energy transfer of rganic luminescent materials manipulated by photonic crystals and offer theoretical evidence and guidance of oligomers in the application of luminescent devices.
