Ng, Man-Kit published the artcilePhotorefractive Effects and Structure/Property Correlation of Oligothiophenes Functionalized with Nonlinear Optical Chromophores, Safety of 2-Bromo-3-(2-ethylhexyl)thiophene, the publication is Chemistry of Materials (2000), 12(10), 2988-2995, database is CAplus.
A homologous series of fully functionalized regioregular oligo(3-alkylthiophenes) 10-12 bearing a nonlinear optical (NLO) chromophore was synthesized. An alternating sequence of bromination and Stille cross-coupling reactions was developed for the synthesis of these oligomers and regiochem. pure, trimethylsilyl-substituted bithiophene organostannane 2c was utilized as the building block. The resulting materials were shown to form stable amorphous films exhibiting a large photorefractive (PR) effect. Two-beam coupling and degenerate four-wave mixing experiments demonstrate large optical net gain and high diffraction efficiency. The PR performance of these oligomers depends on the π-conjugation chain length with an optimized conjugation length.
