Two-photon absorbing cross-linked polyurethanes containing diphenylamino-dialkylfluorene-1,3,5-triazine units |
摘要 |
Two-photon absorbing (2PA), cross-linked polyurethanes were prepared from bis(isocyanato) monomers, tris(isocyanato) monomers or a mixture thereof, in conjunction with novel polyol molecules with donor-acceptor octupolar geometry, whose generic structure is comprised of an electron-accepting 1,3,5-triazine hub with three spokes constituted by electron-donating triarylalkylamine end-groups, which are polyfunctionalized with thermally reactive alcohol functions. The resulting neat glassy or rubbery solids are applicable in a wide range of linear and nonlinear optical applications. |
