Description
技术领域
本发明涉及一种聚合物荧光材料,具体涉及一种含2,6-二苯基-4-芳基吡啶结构的D-π-A型聚合物荧光材料,还涉及其制备方法,属于有机高分子荧光材料技术领域。
背景技术
发光材料是一类具有重要技术意义的功能材料,它们被大量应用于光电器件、太阳能电池和生物传感器等领域。导电高分子材料由于具有光电学性能的同时还具备高分子材料的良好力学性能,所以近些年来共轭聚合物的光学及电学特性研究受到了研究者们广泛关注。与传统的共轭聚合物相比,含氮杂环聚合物引入了吸电子氮杂环单元,可以减小能隙和增强共轭聚合物电子注入与传输性能。这类聚合物由于具有良好的热稳定性、机械加工和性可调性等优点,引起了广大科研工作者的极大的兴趣。
Wang等(Liaw D-J,Wang K-L,Kang E-T,Pujari S P,Chen M-H,Huang Y-C,TaoB-C,Lee K-R,Lai J-Y.Optical properties of a novel fluorene-based thermallystable conjugated polymer containing pyridine and unsymmetric carbazolegroups[J].Journal of Polymer Science Part A:Polymer Chemistry,2009,47(4):991-1002)通过齐齐巴宾反应合成了一种新的含杂环吡啶和咔唑基团的二碘单体,再通过Suzuki偶联反应制备了共轭聚合物PyCz,其合成路线如下所示。所研制的共轭聚合物在室温下易溶于常见的有机溶剂,在氮气环境下,具有较高的热稳定性,其玻璃化转变温度(Tg)为191℃,10%的热失重温度(Td10)为434℃。在HCl溶液中,存在明显的质子化效应,将聚合物溶于THF溶液,通过改变酸的浓度,其最大荧光发射发射波长从400nm处的蓝色区域变为540nm处的黄色区域并且发射强度也受酸的浓度影响。同时,该聚合物在施加电压下也显示出电致变色行为。当施加2.5V偏压时,聚合物膜的发射颜色从蓝色(435nm)变为黄色(570nm)。
Jiang等成功地合成了一类基于芴和2,4,6-三苯基吡啶衍生物的新型聚合物P0-P2(Jiang H-J,Gao Z-Q,Liu F,Ling Q-D,Wei W,Huang W.Novel photoluminescentpolymers containing fluorene and 2,4,6-triphenyl pyridine moieties:Effects ofnoncoplanar molecular architecture on the electro-optical properties ofparent matrix[J].Polymer,2008,49(20):4369-4377)。其合成的所有聚合物在蓝色区域内都能提供较宽的带隙,聚合物P0-P2的结构如下。
Cao等以2,4,6-三(2-噻吩基)吡啶为原料合成了可用于有机场效应晶体管(OFET)的新型共轭聚合物PBDTTPy(Cao K L,Sun X N,Zhang Q,Liu Y Q.Synthesis andcharacterization of a 2,4,6-Tri(2-thienyl)pyridine-based conjugated polymerfor OFET applications[J].Macromolecular Chemistry and Physics,2012,213(9):917-923),合成路线如下所示。该项研究发现,通过在共轭聚合物中引入缺电子吡啶和富电子芴结构单元可以降低聚合物的HOMO能级,从而提高其环境的稳定性;且聚合物PBDTTPy在固态下具有典型的非晶态结构,聚合物薄膜的吸收光谱与其溶液的相比,聚合物薄膜的吸收光谱呈现出较大的红移且连接三噻吩基吡啶单元的共轭聚合物PBDTTPy在OFET器件中能够表现出良好的p型输运,其迁移率为2.4×10-4cm2 v-1s-1。
Buelt等描述了两种含有吡啶结构的共轭聚合物CP和BHP(Buelt A A,Osti NC,Htet Y,Conrad C A,Shehata M F,Potai R,Tennyson A G,Perahia D,Smith RC.Conjugated polymers with m-pyridine linkages:Synthesis,photophysics,solution structure and film morphology[J].Journal of Materials Chemistry C,2014,2(38):8113-8121),其结构如下所示。CP和BHP的共轭段由对2,5-二己氧基苯乙烯、对苯乙烯和2,7-咔唑亚基组成,合成的聚合物主链能够形成规律性的弯曲,因此,每个聚合链中的吡啶单元都能够被包裹在2,4,6-三芳基取代吡啶环所提供的空间裂缝中,从而最大限度地减少这些位点链间的相互作用。光致发光研究表明,该类聚合物链随着溶液浓度的增加,其聚集程度逐渐增大,并且这种聚集在光物理性能上表现为红色的光致发光特性。
现有技术中虽然报道了多种由吡啶环构建的共轭聚合物,但是还未见通过2,4,6-三芳基吡啶通过碳碳三键与给电子共轭体系构建的D-π-A型聚合物荧光材料。
发明内容
针对现有技术存在的缺陷,本发明的目的是提供一种溶解性较好、热稳定性和荧光性能良好的含2,6-二苯基-4-芳基吡啶结构的D-π-A型聚合物荧光材料。
本发明的第二个目的是提供一种原料成本低、步骤简单、反应条件温和的合成含2,6-二苯基-4-芳基吡啶结构的D-π-A型聚合物荧光材料的方法。

其中,
R为氢、C1~C5的烷基、C1~C5的烷氧基或三氟甲基;

本发明的含2,6-二苯基-4-芳基吡啶结构的D-π-A型聚合物荧光材料,其分子结构中的炔基具有一定的电子接受能力,当炔基与吡啶的2,6-苯基相连所构成的吡啶母核时,会增大整个吡啶母核的吸电子能力。同时,炔基作为π桥,将吡啶主体单元和TPE、芴等强给电子能力的给体单元连接起来,可进一步增强聚合物的热稳定性和蓝光发射的高量子产率。此外,吡啶结构中的R基团(烷基、烷氧基以及三氟甲基等),以及咔唑和芴单元中的正辛基,有助于提高共轭聚合物的溶解性能。

1)共轭聚合物的结构表征:
共轭聚合物(5aa~5bd)的合成路线如上所示。经1H NMR和FTIR等方法确定了其结构。代表性聚合物5aa的1H NMR谱图如图4所示,从图4中可以看出,甲基特征峰在化学位移为2.55ppm的高场区中出现,在7.39~8.50ppm处出现的峰为苯环上芳氢吸收峰,所测样品的氢个数和聚合物分子结构相对应,说明得到了预期结构的聚合物。共轭聚合物(5aa~5bd)的FTIR红外光谱图如图5所示,在2250cm–1处出现了较弱的碳碳三键特征伸缩振动吸收峰。
2)共轭聚合物的分子量:
共轭聚合物(5aa~5bd)的分子量测试采用的是凝胶色谱法(GPC)。以四氢呋喃为流动相,在流速为0.3mL/min的条件下进行测试。表1中列出了该系列聚合物的重均分子量(Mw)、数均分子量(Mn)、多分散系数PDI(Mw/Mn)的数值以及聚合物的产率。从表1中可以看出,聚合物的重均分子量在10000~13500之间,多分散系数在3.03~3.75之间,产率为88~93%。
表1.共轭聚合物(5aa~5bd)的产率和分子量
a Weight-average molecular weight was tested by GPC with polystyreneas calibration.
b Number-average molecular weight was tested by GPC with polystyreneas calibration.
c Polydispersity index(PDI=Mw/Mn).
3)溶解度性能:
表2.共轭聚合物(5aa~5bd)的溶解性能a
a Solubility Test:10mg of polymer was added to 1mL solvent for 24h;++:dissolved at room temperature;+-:partially dissolved on heating(50℃);--:insoluble even on heating;NMP:N-methyl-2-pyrrolidone;DMF:N,N-dimethylformamide;DMAc:N,N-dimethylacetamide;
DMSO:Dimethylsulfoxide;THF:Tetrahydrofuran;Py:Pyridine.
由表2可知,该系列共轭聚合物在常温下大都能溶解于DMF、DMAc、DMSO、THF和CHCl3等溶剂,加热后部分聚合物能溶解于丙酮、甲苯和NMP。这可能是由于主链中大体积的结构单元,增加了大分子之间的距离,溶剂分子容易渗入分子链之间;同时,甲基、三氟甲基、炔基和烷基链这些柔性基团的存在也进一步提高了聚合物的溶解性。
4)光学性能:
紫外-可见吸收光谱分析:
采用紫外-可见光谱对共轭聚合物(5aa~5bd)进行测试。首先进行溶液配制,取10μL的1.0×10–3M样品原溶液于1mL的THF溶剂中稀释,配制成浓度为1×10–5M的待测液。然后,使用空白比色皿对紫外可见分光光度计进行基线校准,最后进行待测试样测试。
共轭聚合物(5aa~5bd)在λ=200~800nm之间的紫外-可见吸收光谱曲线如图6所示,其中,200~275nm为π-π*电子跃迁引起;由于电子给体和受体通过炔基形成了D-π-A型极性结构,从而在300~450nm处有一个由分子内电荷转移产生的吸收峰。
同一溶剂下荧光发射光谱分析:
共轭聚合物(5aa~5bd)在溶液中可也发出不同程度的荧光。为了进一步探索5aa~5bd的发光性能与其结构的关系,对该系列共聚物进行了荧光发射波长的测试,溶液配制方法与紫外-可见光谱测试类似,测试结果如图7所示。在测试其荧光发射波长时,以λex=378nm、379nm、374nm、371nm、359nm、376nm、373nm和390nm作为化合物5aa~5bd的激发波长,并同一设置狭缝和电压,相关测试数据如表3所示
从图7中可以发现共轭聚合物(5aa~5bd)的最大发射波长为400nm左右,而当3a和3b分子接入TPE形成D-π-A型共轭聚合物时其最大发射波长出现了明显的红移,如聚合物5ab和5bb两种聚合物的最大发射波长为507nm和520nm,溶液发出黄色的荧光,这可能是由于TPE中的四个苯环可以自由旋转,增强了其分子内的电荷转移。
共轭聚合物(5aa~5bd)在溶液状态下都能发出不同程度的荧光(图8),但固体状态下的荧光却非常微弱,表明,虽然所设计制备的D-π-A聚合物增强了其电子传输性能,在溶液中的荧光性能得到提高,但由于聚合物的共轭链增大,ACQ效应也更加明显,导致固体发光减弱。
表3.共轭聚合物(5aa~5bd)的荧光发射光谱测试数据

b The wavelength of excitation maximum.
c The wavelength of emission maximum.
不同溶剂下荧光发射光谱分析:
从上述研究中可以发现,共轭聚合物(5aa~5bd)在溶液中的荧光性能较好,为此继续研究溶剂化效应对其荧光性能的影响。先将1.0×10–3M的样品原溶液分别用甲苯、二氯甲烷、四氢呋喃、乙腈、DMSO等五种溶剂稀释成1.0×10–5M的待测溶液(图9和图10),均以激发波长为390nm来测定该系列聚合物的荧光发射波长。
从图9和图10可知,在这些溶剂中,共轭聚合物荧光发射波长并没有很大的区别。其中5ac和5bc这两种聚合物随着溶剂极性的增大,其发射波长随之出现了轻微红移的现象。5ab和5bb在乙腈溶液中发生了明显的蓝移,这可能是由于电子在n-π*跃迁时,n电子在基态时与乙腈容易形成稳定的氢键而不易产生能级跃迁,因而使跃迁需要的能量增加,所以引起吸收带蓝移。总体而言,该系列聚合物的最大发射波长受溶剂极性的影响较弱。图11为共轭聚合物(5ab、5ac、5bb和5bc)在紫外灯照射下,溶于不同溶剂的荧光照片。
5)电化学性能:
使用循环伏安法(CV)测定共轭聚合物(5aa~5bd)在除水脱氧的CH3CN溶液中的氧化还原电位,并计算其HOMO和LUMO能级。扫描速度为50mV s–1,0.1M四丁基四氟硼酸铵(TBABF4)作为电解质,二茂铁(Fc-Fc+)作为外部标准进行校准。铂丝作为对电极,Ag/AgCl电极作为参比电极。取5mg聚合物溶于1mL已除氧的THF溶液中,再将聚合物沉积在工作电极上进行测试。
共轭聚合物(5aa~5bd)的CV曲线如图12所示,电化学数据列于表4。8种共轭聚合物氧化电位的起始电位分别为+1.83eV、+1.37eV、+1.32eV、+1.64eV、+1.13eV、+1.73eV、+1.20eV和+1.03eV。根据EHOMO=-(4.8+Eox-EFc-Fc+)和ELUMO=EHOMO+Eg计算,得到聚合物的最高占据分子轨道HOMO和最低未占据分子轨道LUMO能级。聚合物的HOMO/LUMO能级分别为-6.23/-3.15eV、-5.77/-3.32eV、-5.72/-2.67eV、-6.03/-2.91eV、-5.53/-2.33eV、-6.13/-3.74eV、-5.60/-2.58eV和-5.43/-2.36eV,通过Eg=1240/λem(λem为起始发射波长)计算该系列化合物的能级带隙在2.39~3.20eV之间。这表明该类共轭聚合物的能级可以通过改变聚合物主链上的供体和受体来有效调节。

b Eox determined from the onset potentials of the oxidation waves.
cEHOMO=-(4.8+Eox-EFc-Fc+),ELUMO=EHOMO+Eg,Eg=1240/λem(λem=Initial emissionwavelength).
6)结晶性能:
从广角X-射线衍射(WAXD)曲线(图13)可知,该系列共轭聚合物呈现出宽而弥散的峰型,说明聚合物均为无定型结构,这主要是由于大体积的吡啶结构单元,以及大体积的TPE、咔唑、芴等结构单元引入分子主链,使聚合物分子之间的距离增大,削弱了分子间的作用力,导致大分子无法进行有序排列,从而大大降低了聚合物的结晶性。
7)热学性能:
良好的热稳定性是保证聚合物能否应用于器件的首要条件。在氮气环境下,采用热失重(TGA)和差示扫描量热法(DSC)方法对共轭聚合物(5aa~5bd)的热性能进行了分析测试,相应的数据列于表4。TGA曲线和DSC曲线分别如图14和图15所示。从表4可知,聚合物失重10%时的热分解温度为364~481℃,在800℃时,残碳率为34.9~70.7%,说明该系列聚合物具有良好的耐热性。此外,上述共轭聚合物的DSC曲线没有明显的玻璃化转变温度。
