We report the synthesis and optical properties of organic porphyrin nanoparticles with narrow size distribution and good dispersibility. Nanoparticles were produced by a combination of precipitation and sonication, termed the "ultrasonic method". The resulting [tetrakis(para-chlorophenyl)porphyrin]TClPP nanoparticles were stable in solution without precipitation for at least 30 days. No self aggregation of the constituent porphyrin chromophores was observed. The TClPP nanoparticles exhibited interesting optical properties, particularly a large bathochromic shift in the absorption spectra.

我们报告了具有窄尺寸分布和良好分散性的有机卟啉纳米粒子的合成和光学性质。纳米粒子是通过沉淀和超声的组合（称为“超声法”）制备的。所得的[四（对氯苯基）卟啉]TClPP 纳米粒子在溶液中稳定，至少 30 天内没有沉淀。没有观察到组成卟啉发色团的自聚集。TClPP 纳米粒子表现出有趣的光学性质，特别是在吸收光谱中观察到较大的红移。
