5,10,15,20-四(1-甲基-4-吡啶基)卟啉四(对 甲苯磺酸盐)（TMPyP），是一种带正电荷的双光子染料，可以与细胞培养物中的DNA结合并影响细胞活力。据报道，通过长期包封TMPyP纳米颗粒，可防止染料与细胞直接接触，但染料仍可在暴露于红外光时通过产生单线态氧而杀死细胞。通过水热多元醇工艺可制备TMPyP官能化石墨烯负载的铂纳米颗粒催化剂。据报道，TMPyP与白色念珠菌（Candida albicans）一起孵育时，表现出出色的1O2发光信号。通过光激发，TMPyP能够与化学还原的石墨烯氧化物发生电荷转移相互作用。据报道，它也是一种很有前景的光动力疗法光敏剂。 5,10,15,20-四(1-甲基-4-吡啶基)卟啉四(对甲苯磺酸盐)（TMPyP），是一种阳离子卟啉，用于研究石墨烯与阳离子卟啉通过UV-vis和荧光方法发生的非共价官能化。TMPyP可用作制备多功能膜的光学指示剂配体，用于视觉警告以及增强水溶液中镉离子的吸附去除。TMPyP还被用于从非共价吸附复合材料制备（TMPyP）-单壁碳纳米管（SWNT）/叶绿素铜钠-SWNT逐层组装复合膜。 TMPyP [=α,β,γ,δ-Tetrakis(1-methylpyridinium-4-yl)porphyrin p-Toluenesulfonate] (TMPyP) is a positively charged, two-photon dye, that can bind to DNA in cell cultures and affect the cell viability. Long term encapsulation of TMPyP by nanoparticles is reported to prevent the dye from direct contact with cells, but the dye can still kill the cells via singlet-oxygen production on exposure to infrared light. Nanostructured catalyst of platinum nanoparticles supported on TMPyP functionalized graphene is prepared by hydrothermal polyol process. TMPyP is reported to show excellent 1O2 luminescence signals on incubation with the fungus, Candida albicans. On photoexcitation, TMPyP undergoes charge-transfer interaction with chemically reduced graphene oxide. It is also reported to be a promising photodynamic therapy photosensitizer. TMPyP [=α,β,γ,δ-Tetrakis(1-methylpyridinium-4-yl)porphyrin p-Toluenesulfonate] (TMPyP), a cationic porphyrin, was used to study the noncovalent functionalization of graphene with cationic porphyrins using UV-vis and fluorescence methods. TMPyP may be used as an optical indicator ligand in the preparation of multifunctional membrane for visual warning and enhanced adsorptive removal of cadmium ions in aqueous solutions. TMPyP was also used to fabricate the (TMPyP)- single-walled carbon nanotubes (SWNT)/sodium copper chlorophyllin-SWNT layer-by-layer film from noncovalently adsorbed composites.
