Background: Nanomaterials based on porphyrin has attracted attention for significant research due to their potential applications in diverse fields such as optoelectronic devices, catalysis, light harvesting devices, controlled-release drug delivery. The self assembly method is an effective protocol for the fabrication of nanomaterials. Objective: We synthesized an unsym. porphyrin 5,10-bis(4-hydroxyphenyl)-15,20-bis(4-pyridyl) porphyrin, decorated with hydroxyl and pyridyl functional group which assist in supramol. self assembly. Method: We used two different methods, surfactant assisted method and vaporization-condensationrecrystn. method for the self assembly of our new unsym. porphyrin bearing hydrogen bonding motifs. The nanoaggregates obtained by these two different methods were well characterized by different spectroscopic techniques such as UV-visible spectra, fluorescence emission spectroscopy, SEM and X-ray diffraction. Results: A new unsym. porphyrin was synthesized and used for the formation of different nanoaggregates. The surfactant assisted method results in fabrication of nanoboats while VCR method leads to the formation of well ordered nanospindles. Both the nanoboats and nanospindles were formed by virtue of the cooperation of the non-covalent interactions such as hydrogen bonding and – interactions. Conclusion: The vaporization-condensation-recrystallization method forms highly crystalline nanospindles as it induces re-crystallization based self-assemblies using externally provided thermal energy, and avoids the need for solvent mols. while surfactant assisted method requires the solvent as well external stabilizer. In the experiment, the researchers used many compounds, for example, Pyridinehydrochloride (cas: 628-13-7Application In Synthesis of Pyridinehydrochloride).
Pyridinehydrochloride (cas: 628-13-7) belongs to pyridine derivatives. In contrast to benzene, Pyridine’s electron density is not evenly distributed over the ring, reflecting the negative inductive effect of the nitrogen atom. One of the examples of pyridines is the well-known alkaloid lithoprimidine, which is an A3 adenosine receptor antagonist and N,N-dimethylaminopyridine (DMAP) analog, commonly used in organic synthesis.Application In Synthesis of Pyridinehydrochloride
