Here, we present previously synthesized azo and azo-azomethine dyes as thin films in PMMA matrix in order to investigate their spectral and optical properties. The spectral properties of the vapour deposited 100 nm nanosized films of the dyes have been characterized by UV-VIS and Fluorescence ...
Moreover, uniform-sized poly(methyl methacrylate) (PMMA) particles were prepared to use as a probe matrix and 3 was incorporated in the PMMA particles during dispersion polymerization, which can be a sensitive and selective sensor platform for ethylenediamine. 展开 ...
PMMA matrixaldehydefluorescencedispersion polymerizationFluorescent 3′,6′-bis(octyloxy)-p-terphenyl-4,4′-dialdehyde 3 has been successfully synthesized via a Suzuki cross-coupling reaction of the corresponding dibromo compound with a boronic acid compound in the presence of palladium catalyst. The ...

聚甲基丙烯酸甲酯(PMMA)俗称有机玻璃，是目前塑料中透明性最好的品种之一，具有突出的耐老化性和化学稳定性，良好的绝缘性和加工性，与普通无机玻璃相比，体现出质轻高韧的特点，已经被广泛应用于农业、航空、建筑、光学仪器、灯具装饰等领域。但与其他透明塑料相比，PMMA 冲击强度低，耐热、耐磨及耐划伤性差，使其...
For both the dyes Polymehtylmethacrylate-Methacrylic acid (PMMA-MA) has been chosen as a matrix because of its easy availability and easiness of processing. We have used Z-scan technique with CW laser @ 532 nm to study nonlinear optical properties of these materials. The closed aperture Z-...
