Abstract

In this study, we synthesized a triphenylamine-functionalized polytyrosine (PTyr-TPA) through living ring opening polymerization with 4,4'-diamino-4″-methoxytriphenylamine (TPA-NH₂) as an initiator, and used Fourier transform infrared (FTIR) and nuclear magnetic resonance spectroscopy to confirm the chemical structure. Photoluminescence spectroscopy revealed the photophysical properties of TPA-NH₂ and PTyr-TPA and suggested that TPA-NH₂ exhibited aggregation-caused quenching; in contrast, attaching the initiator to the rigid rod conformation of the PTyr segments caused PTyr-TPA to display aggregation-induced emission behavior. Differential scanning calorimetry revealed single glass transition temperatures for miscible PTyr-TPA/P4VP blends, the result of intermolecular hydrogen bonding between the pyridine units of P4VP and the phenolic OH units of PTyr-TPA, as confirmed through FTIR spectroscopic analyses. Furthermore, the chain behavior of PTyr-TPA transformed from a β-sheet conformation to random coils after blending with P4VP, as determined using wide-angle X-ray diffraction. These findings suggest that the decreased emission intensity of PTyr-TPA resulted from release of the restricted intramolecular rotation of the triphenylamine moiety in the polypeptide center.

摘要

在本研究中，我们以4,4'-二氨基-4″-甲氧基三苯胺（TPA-NH₂）为引发剂，通过活性开环聚合反应合成了三苯胺功能化的聚酪氨酸（PTyr-TPA），并使用傅里叶变换红外光谱（FTIR）和核磁共振光谱对其化学结构进行了确认。光致发光光谱揭示了TPA-NH₂和PTyr-TPA的光物理性质，表明TPA-NH₂表现出聚集诱导猝灭；相反，将引发剂连接到PTyr链段的刚性棒状构象上，使得PTyr-TPA表现出聚集诱导发光行为。差示扫描量热法揭示了可混溶的PTyr-TPA/P4VP共混物的单一玻璃化转变温度，这是P4VP的吡啶单元与PTyr-TPA的酚羟基单元之间分子间氢键作用的结果，FTIR光谱分析证实了这一点。此外，使用广角X射线衍射测定，与P4VP共混后，PTyr-TPA的链行为从β-折叠构象转变为无规卷曲。这些发现表明，PTyr-TPA发射强度的降低是由于多肽中心三苯胺部分受限的分子内旋转的释放所致。
