Dithienylethene photochromic switching units have been incorporated into a hydrogelating system based on a tripeptide motif. The resulting hybrid system provided both a photochromic response and the ability to gelate water under acidic and neutral conditions. Fluorescence spectroscopy shows that the dithienylethene units are in sufficient proximity to each other to stack in gel fibers, with the tripeptide
二噻吩基乙烯光致变色转换单元已被并入基于三肽基序的水凝胶化系统中。所得的混合系统既提供了光致变色响应,又提供了在酸性和中性条件下使水胶凝的能力。荧光光谱显示二噻吩乙烯单元彼此足够接近以堆叠在凝胶纤维中,其中三肽单元确定溶解度。TEM测量提供了对所形成的纤维的微观结构的了解。
