Two-photon absorption and the electrochemical properties of a conjugated heteroaromatic chromophore

实验研究了一种新的共轭杂环化合物9-乙基-3-{5-(4-叔丁基苯基)-[1,3,4]-噁二唑-2-苯乙烯基}-咔唑(VBPOEC)的双光子吸收性质和电化学性质.双光子吸收截面采用非线性透过率法测定,双光子最大吸收波长位于800nm,吸收截面为1350GM.采用紫外光谱的边带吸收法得到带隙为2.77eV,用循环伏安法对其电化学性质进行了初步研究,氧化电位为1.059V,其HOMO能级为-5.80eV,其LUMO轨道能级为-3.03eV.研究了光学、电化学性质与分子电子结构的关系.
