【摘要】：酞菁鈷(CoPe)是一種18π電子大雜環(huán)共軛體系的有機(jī)小分子半導(dǎo)體材料,由于同質(zhì)多晶性,具有許多的光電和磁學(xué)性質(zhì),在有機(jī)光伏器件、OLED器件和有機(jī)場效應(yīng)晶體管器件有諸多的應(yīng)用潛力。有機(jī)氣相沉積法是制備酞菁納米材料的重要方法之一。 本論文的主要工作是研究CoPe納米材料與有機(jī)氣相沉積實(shí)驗(yàn)參數(shù)之間的關(guān)系,并表征CoPc納米材料的光學(xué)性質(zhì)。在實(shí)驗(yàn)過程中,通過調(diào)控沉積參數(shù),如溫度場、載氣流量、溫度梯度、襯底材料和沉積時(shí)間等制備CoPe納米線。在大量的實(shí)驗(yàn)工作之后,確定了CoPe納米線最佳的有機(jī)氣相沉積實(shí)驗(yàn)參數(shù)：載氣流量為400sccm,沉積腔室保持為常壓,源材料加熱到450℃。 CoPe納米線具有新的物相,直徑在50-60nm的范圍內(nèi)。CoPe納米線在空氣中非常穩(wěn)定；但在溶液中,它的形貌特征會(huì)發(fā)生顯著的變化。襯底材料以及襯底表面的粗糙度對CoPe納米線的生長沒有影響。XRD研究表明：CoPe納米線有一種新的物相,命名為J-CoPc。J-CoPc納米線的FTIR和UV-Visible吸收光譜不同于其他晶型的CoPc。J-CoPc的特征紅外吸收峰位于731.33cm-1、777.94cm-1和914.38cm-1處。J-CoPc的吸收峰在B帶位于310nm；在Q帶有兩個(gè)吸收峰,分別位于600nm和730nm。
[Abstract]:Cobalt phthalocyanine (CoPe) is a small organic semiconductor material with 18pi electron heterocyclic conjugated system. Because of its homogeneous polycrystallinity, CoPe has many photoelectric and magnetic properties. It has many potential applications in organic photovoltaic devices, OLED devices and airport effect transistor devices. One of the laws.
The main work of this dissertation is to study the relationship between CoPe nanomaterials and experimental parameters of organic vapor deposition and characterize the optical properties of CoPc nanomaterials.During the experiment, CoPe nanowires were prepared by controlling deposition parameters such as temperature field, carrier gas flow, temperature gradient, substrate material and deposition time. Then, the optimum parameters of organic vapor deposition of CoPE nanowires were determined: carrier gas flow was 400 sccm, deposition chamber was kept at normal pressure, and source material was heated to 450 C.
CoPe nanowires have new phases with diameters ranging from 50 nm to 60 nm. CoPe nanowires are very stable in air, but their morphology changes dramatically in solution. The substrate materials and the roughness of the substrate surface have no effect on the growth of CoPe nanowires. XRD studies show that CoPe nanowires have a new phase, named after. The FTIR and UV-Visible absorption spectra of J-CoPc.J-CoPc nanowires are different from those of other crystalline CoPc.J-CoPc nanowires. The characteristic infrared absorption peaks of J-CoPc nanowires are located at 731.33 cm-1,777.94 cm-1 and 914.38 cm-1. The absorption peaks of J-CoPc nanowires are located at 310 nm in B band and at 600 nm and 730 nm in Q band, respectively.
