【摘要】 本工作中,我们设计合成了两亲性BODIPY衍生物(BN1),并利用微转印技术制备了离子液体微阵列担载的气液传感界面。基于BN1的氨基与DCP之间的特异性化学反应,分子内的PET效应消失,荧光强度增强,从而实现了对DCP的"turn-on"传感。由于两亲分子BN1在微阵列化的离子液体气液界面上的表面富集特性,使得气体分子和荧光物种直接作用,提高了传感薄膜的响应速度和灵敏度。更多还原

【Abstract】 In this work, an amphiphilic BODIPY derivative(BN1) was designed and synthesized. The gas-liquid sensing interface which loads on ionic liquid microarrays was fabricated by the microcontact printing technology. The sensing mechanism is based on a specific reaction between phosphoryl halides and the fluorescent probe BN1. When BN1 functionalized ILs microarrays are dipped in the DCP vapor, the reaction of amino unit with phosphorus oxychloride moiety blocks the PET process between amino group and BODIPY structure, leading a rapid and obvious increase in fluorescence intensity. The interfacial self-assembling of the amphiphilic molecule, BN1, can avoid the mass transfer limitation and improve the response speed and sensitivity of the sensing films largely.更多还原
