| 中文摘要 | a series of eight new polyquinolines and polyanthrazolines with pyrrole isomeric units in main chain were synthesized and characterized. the new polymers showed high glass transition temperatures (t-g = 242-339 degreesc) and excellent thermal stability (t-5% = 398-536 degreesc in air, tga). compared to the series of polyanthrazolines, the series of polyquinolines exhibited higher thermal stability, better solubility in common organic solvents, and lower maximum absorption wavelengths (lambda(max)(a)). polyanthrazolines with 2,5-pyrrole linkage showed an unusually high lambda(max)(a) (565 nm) and small band gap (2.02 ev). all polymers in solution had low photoluminescence quantum yields between 10(-2%) and 10(-5%) and excited-state lifetimes of 0.28-1.29 ns. the effects of molecular structure, especially pyrrole linkage structures, on the electronic structure, thermodynamics, and some of the optical properties of the polymers were explored. a model of hydrogen bonds in the main chain of the polymers was suggested to explain the difference in the properties of the isomer polymers. in addition, a polyquinoline (pbm) was chosen to examine the proton conductivity; the result indicated that the pbm/h3po4 complex exhibited a high conductivity of 1.5 x 10(-3) s cm(-1) at 157 degreesc. |
