摘要：

Two new poly(arylene ether sulfone)s (P1 and P2) with two new accepting group (TCF)-based chromophores (1 and 2) in side chains, respectively, were designed and synthesized. The two chromophores contain the same electron donating group (dialkylamino group) and the same accepting group (TCF), but different conjugation bridges. Compound 2 contains a combined conjugation bridge (phenyl-diazene plus styrene), but the bridge of 1 is much shorter (styrene only). A variety of optical properties were studied. Compared with P1, P2 exhibited comparable nonlinear optical coefficient (d(33)) and better transparency (the maximum absorption was blue-shifted by 16 nm), though the conjugation bridge of chromophore 2 in P2 was much longer than that of 1 in P1. This result may help design nonlinear optical polymers achieving the balance between nonlinearity and transparence against the intrinsic trade-off.
