The influence of morphology on the photoconductive properties of binary ionic porphyrin assemblies is examined. Micro-to millimeter sized crystalline rods and complex hyperbranched structures, or sheaves, were grown in a controlled manner by combining stoichiometric amounts of meso-tetra(4-aminophenyl)porphyrin, H 2 [H 2 TAPP] 2+ , and meso-tetra(4-sulfonatophenyl)porphyrin, [H 4 TSPP] 2− , metal-free ionic tectons. The H 2 TAPP:H 4 TSPP structures were characterized by X-ray diffraction, microscopic methods, optical spectroscopy, conductivity and photoconductivity measurements. The two different H 2 TAPP:H 4 TSPP morphologies (rods and sheaves) exhibit similar molecular organization and crystal structure but possess different optoelectronic properties. The rods and sheaves exhibit weak dark conductivity and become more conducting upon illumination into the tetrapyroles Soret and Q bands. The primar...

离子卟啉晶体组件的形态学依赖性电导率和光电导率

研究了形态对二元离子卟啉组件的光电导性能的影响。通过将化学计量的介孔四（4-氨基苯基）卟啉，H 2 [H 2 TAPP] 2+和介孔四价化学计量相结合，以受控方式生长微米级至毫米级的晶体棒和复杂的超支化结构或滑轮。 （4-磺酰基苯基）卟啉，[H 4 TSPP] 2−，无金属离子构造。通过X射线衍射，显微方法，光谱，电导率和光电导率测量来表征H 2 TAPP：H 4 TSPP结构。两种不同的H 2 TAPP：H 4 TSPP形态（杆和绳轮）显示相似的分子组织和晶体结构，但具有不同的光电特性。杆和滑轮显示出较弱的暗电导率，并且在照射到四吡咯索雷特和Q带中变得更导电。原始...
