Aqueous media acts as a functional component for the metal carbonyl vesicles (MCsome) assembled from FpC₃Bithiophene (Fp: (Cp)Fe(CO)₂(PPh₃), C₃: propyl) molecules. The MCsome in THF/water (with the ratio up to 0.30) have an aqueous vesicular membrane, which integrates the assembling blocks and restricts the intramolecular rotation of bithiophene groups. The restriction fixed the relative position of the aromatic groups giving rise to a through-space conjugation (TSC), which is responsible for the fluorescence with the wavelengths and intensities depending on the twisting angle of bithiophene groups. A dialysis process to remove THF trigged a torsional-to-planar rotation switching off the fluorescence, while the irradiation of UV light (wavelength 365 nm) stimulated a planar-to-torsional rotation for the solutions in THF/water mixed solvents, which turned on the fluorescence. This aqueous-mediated TSC-caused fluorescence signifies that water, as in natural systems, can act as a structural and functional component for material innovation.

水性介质充当由FpC ₃ Bithiophene（Fp：（Cp）Fe（CO）₂（PPh ₃），C ₃组装而成的羰基金属囊泡（MCsome）的功能成分：丙基）分子。THF /水中的MCsome（比例最高为0.30）具有水泡膜，该泡囊膜整合了组装块并限制了联噻吩基团的分子内旋转。限制条件固定了芳香族基团的相对位置，从而产生了贯穿空间的共轭（TSC），该共轭（TSC）负责荧光，其波长和强度取决于联噻吩基团的扭曲角。去除THF的渗析过程触发了扭转到平面旋转，从而关闭了荧光，而紫外线（波长365 nm）的照射刺激了THF /水混合溶剂中溶液的平面到扭转旋转，该旋转变成了在荧光上。由水介导的TSC引起的荧光表示水，就像在自然系统中一样，
