摘要
High refractive index polymers (HRIPs) are essential materials for many optical applications, including organic light-emitting diodes (OLEDs), charge-coupled devices (CCDs), complementary metal oxide semiconductors (CMOS), eyeglasses, and optical waveguides. Various molecular designs, synthetic routes, and material preparation methods have been reported to increase the refractive index (RI) of polymers; however, increasing the RI using only organic (and classical) components is difficult. Other properties, such as low or high Abbe numbers (RI dispersion), low birefringence, and high transparency, are also required for HRIPs depending on the intended wavelength usage, which ranges from visible to infrared (IR) light and X-ray applications. This review summarizes the recent developments in HRIPs, including their synthesis, properties, and applications, and provides future prospects for achieving HRIPs with the desired performances. This review summarizes recent molecular design of high refractive index polymers including their synthesis, relationships between other properties, and applications. Discussions on how to make polymers further refractive while exhibiting visible transparency, which is generally a difficult issue contrary to the empirical threshold for optical polymers, will also be discussed by focusing on the control of multi-scale molecular structures.
