Yeast capsules (YCs) produced from with encapsulated fluorescent phenosafranin and azure dyes were used as catalytic template guides for developing hybrid functional organic/inorganic hollow microstructures with silica (SiO) deposited on their surface generated in the imidazole-buffered system without the addition of any cationic surfactant. YCs-doped with SiO act as fluorescence emitters maintaining dye-loaded materials by sealing the microporous surface of YCs. We used vinyltrimethoxysilane as a precursor of SiO endowed with functional vinyl groups facilitating their further modification without disturbing the polysaccharide wall integrity. Consequently, the hybrid fluorescent polysaccharide/silica microcapsules (YC@dye@SiO) are promising for wide-ranging optoelectronic applications in electrochromic and OLED devices with biocompatibility and biodegradability properties.
酵母胶囊（YC）由 制成，内部封装了荧光 phenosafranin 和 azure 染料，被用作催化模板导向，用于在咪唑缓冲体系中，无需添加任何阳离子表面活性剂的情况下，在其表面沉积二氧化硅（SiO），生成具有混合功能的有机/无机中空微结构。掺杂 SiO 的 YC 作为荧光发射器，通过密封 YC 的微孔表面来保持负载染料的材料。我们使用乙烯基三甲氧基硅烷作为 SiO 的前体，赋予其功能化的乙烯基基团，便于进一步修饰，而不会破坏多糖壁的完整性。因此，具有生物相容性和可生物降解性的混合荧光多糖/二氧化硅微胶囊（YC@dye@SiO）有望在电致变色和 OLED 器件等广泛的光电应用中得到应用。
