微球由邻苯二甲酰亚胺取代的卟啉衍生物制成。显微镜分析表明，在本研究中合成的超分子组装体的结构是球形的，直径在亚微米至微米范围内。通过改变铸膜液的浓度可以控制微球的尺寸。测量微球的光谱性质以确定其结构组分的影响。热研究表明，这些结构变得不稳定的温度低于体熔点。在对由这些微球组成的器件进行I-V测量时，发现在光照射下电流增加，并且这些器件的特征光响应特性是可再现的。
Microspheres were fabricated from phthalimide‐substituted porphyrin derivatives. Microscopic analysis showed that the structures of the supramolecular assemblies synthesized in the present study were spherical, with diameters in the sub‐micrometer to micrometer range. The size of the microspheres could be controlled by changing the concentration of the casting solution. The spectroscopic properties of the microspheres were measured to determine the influence of their structural components. Thermal studies indicated that the temperature at which these structures became unstable was lower than the bulk melting point. DuringI–Vmeasurements on devices composed of these microspheres, it was found that the current increased upon light irradiation, and the characteristic photoresponse properties of these devices were reproducible.
