【摘要】:有机光电功能材料广泛应用于有机电致发光器件(OLED)、有机光伏器件(OPV)、有机场效应晶体管(OTFT)以及非线性材料、荧光探针和太阳能电池等方面,近年来一直是研究领域的热点。螺二芴类化合物具有特殊的三维空间结构和电子效应,而三苯胺具有较高的空穴迁移率和良好的传输性能,一直被广泛应用于各种功能材料中。所以本文设计将三苯胺与螺二芴结合起来,以期得到具有螺二芴和三苯胺共同特点的具有多种性能的化合物。本文主要做了以下工作:第一部分:设计了一条廉价可行的合成螺二芴类化合物的路线,合成了五种以2,7-二(三苯胺)基螺二芴为母体的化合物:SPF-TMA、SPF-TAA、SPF-TNP、SPF-TCA、SPF-TMC,以及两种对照化合物SPF-NP、SPF-CA。第二部分:研究了SPF-TNP的相关性能。1,研究表明其热稳定性良好(Td=289℃);2,光谱性质、电化学性质和电致发光性能研究表明其可兼作发光材料和空穴传输材料;3,研究表明其是一个双光子p H探针,p Ka为2.52,双光子吸收截面为686GM;4,研究表明其可以对四氢呋喃和1,4二氧六环中的含水量进行检测,检测极限分别为0.049%和0.018%。第三部分:1,研究了SPF-TCA、SPF-TMC和SPF-CA的光谱性质、电化学性质,并将其作为染料敏化剂制作成太阳能电池器件,器件的光电转换效率分别为0.63%、0.55%和0.48%。2,研究了SPF-TMC对有机溶剂DMSO、DMF、丙酮中含水量检测性能,其检测极限分别为0.017%、0.018%和0.045%;以及SPF-TMC的p H检测性能,表明SPF-TMC可以作为一个p H探针,其p Ka为5.95。第四部分:研究表明SPF-TMA是一个p H探针,其p Ka为7.57。而SPF-TAA是一个双光子p H探针,其p Ka为2.21,双光子吸收截面为1335GM。
[Abstract]:Organic optoelectronic functional materials are widely used in organic electroluminescent devices (OLED), organic photovoltaic devices (OPV), have airport effect transistor (OTFT) as well as nonlinear materials fluorescent probes and solar cells and so on. In recent years organic photovoltaic devices have been a hot research field. Spirodifluorene compounds have special three-dimensional spatial structure and electronic effect, while trianiline has been widely used in various functional materials because of its high hole mobility and good transport performance. Therefore, in this paper, we design a combination of trianiline and spirodifluorene in order to obtain a variety of compounds with the common characteristics of spirodifluorene and trianiline. The main works are as follows: in the first part, a cheap and feasible route for the synthesis of spirodifluorene compounds was designed. Five kinds of SPF-TMA-SPF-TAAMA-SPF-TNPN SPF-TNPN SPF-TCAF-TMCand two control compounds SPF-NPV SPF-CAF-CAA were synthesized. Part two: the related properties of SPF-TNP were studied. 1. The results showed that the SPF-TNP had good thermal stability (Td=289 鈩,
