Synthesis and optical properties of NLO chromophores containing an indoline donor and azo linker

摘要: Abstract A suite of new nonlinear optical chromophores containing an indoline donor and azo linker has been synthesized in high yields. The methodology used allows for the incorporation various acceptor systems, ready isolation target compounds access to materials with excellent thermal stabilities (viz = Td 220–270 °C). first hyperpolarizabilities were measured by hyper-Raleigh scattering all found have response. highest value was 1640 × 10−30 esu DMF at 800 nm a chromophore well-known TCF system. Based on data obtained this other studies, there is evidence that donors are capable providing molecular NLO responses higher than those derived from N,N-disubstituted anilines.
