A tetraphenyl porphyrin derivative with two C(16) alkyl chains covalently bound to each of the four peripheral phenyl rings through ether linkages formed multilayer clusters or vesicles at the air-water surface. More interestingly, spherical vesicles were also formed when deposited on appropriate solid surfaces, and these vesicles were stable even in dry conditions. Various microscopic images of the cast film deposited on a mica surface confirmed closed-ended nanotube/nanorod-type formation with necking and bulging. These narrow tubes are proposed to be intermediates for the formation of vesicles by fission at either side of the bulge. Such vesicular formation is not common when either cast or Langmuir-Blodgett films were deposited on a solid surface.
一种四苯卟啉衍生物，其四个外围苯环通过醚键共价连接到两条 C(16) 长链烷基上，在空气-水界面形成多层聚集体或囊泡。更有趣的是，当沉积在适当的固体表面上时，也形成了球形囊泡，即使在干燥条件下这些囊泡也很稳定。沉积在云母表面的涂膜的各种微观图像证实了具有缩颈和凸起的封闭端纳米管/纳米棒型形成。这些狭窄的管被提议为通过在凸起两侧的分裂形成囊泡的中间体。当在固体表面上沉积铸造或 Langmuir-Blodgett 膜时，通常不会发生这种囊泡形成。
