“…Highrefractive index, optical transparency and low birefringence are the most important factors in optical applications. According to the Lorentz-Lorenz equation, the introduction of substituents with high-molar refractions and low-molar volumes can efficiently increase the refractive index of polymers (5)(6)(7)(8)(9). Among the various substituents, the sulfur atom, which has high atomic refraction, is one of the most effective candidates.…”

Two kinds of new aromatic diamine monomer containing thio-amide unit, bis [4-(p-aminothiophenyl)benzoyl]diamine (ATPBA), were synthesized in two steps, which was reacted with 4,4 -(sulphonyl-bis(p-phenylthio)) dibenzoyl chloride (S-DC) to prepare a new polyamide containing high quantity thio-ether unit. The intrinsic viscosity of PASSA was 0.81-0.93dl/g obtained with optimum synthesis conditions. The polymers were found to have excellent thermal performance with glass transition temperature (T g ) of 245.3-265.8 • C, initial degradation temperature (T d ) of 446.9-441.6 • C. They showed improved solubility in polar aprotic solvents. The optical transmittance of the aromatic polyamide (PA-3a and PA-3b) film at 450 nm is higher than 80%. The thio-ether unit provided the PA-3a and PA-3b with a much higher refractive index ranging from 1.699 to 1.701, and low birefringence between 0.006 and 0.007.

“…In bridged and non-polar polycyclic hydrocarbon structures, rigidity and three-dimensional size contribute to a high free volume, low moisture absorption and absence of π-electrons to lower the dielectric constant and increase optical transparency in the visible region [5][6][7][8][9][10][11][12][13]. Consequently, we hypothesized that incorporation of bulky, rigid tricycloalkyl substituents into PMMA would improve the thermal and mechanical properties of the polymer and maintain good optical and dielectric properties to result in high-performance, high-value materials for use in microelectronic and optoelectronic applications.…”

Colorless and transparent polymers with high refractive indices and high temperature resistance have aroused great interest in the industrial community. Here, a series of polyimides (PIs) were prepared from a newly synthesized thioether-containing dianhydride, 1,4-bis(3,4-dicarboxy-phenylenesulfanyl)-benzene dianhydride, and various diamines by a two-step polycondensation reaction. Some flexible and tough films were obtained by casting solutions of them in poly(amic acid) (PAA). The tensile strengths and elongations at break of these PI films were greater than 58 MPa and 10%, respectively. All of them were thermally stable up to 500°C in both air and nitrogen. Their glass transition temperatures were in the range from 204.5 to 265.8°C. PI films with a thickness of 10-20 μm showed good optical transparency in the visible light region. Their cutoff wavelengths were lower than 400 nm and their transmittance was higher than 80% at 460 nm. The thioether linkages in the PIs endowed them with high average refractive indices (n AV ) of 1.68-1.74 and low birefringence values (Δn) of 0.0085-0.0120.
