IntisariSintesis dan fabrikasi lapisan tipis berbasis nanopartikel porphyrin alam dilaporkan pada makalah ini. Larutan porphyrin alam disintesis melalui proses permurnian dengan teknik kolom kromatografi kemudian ditumbuhkan menjadi lapisan di atas substrat Cu dengan metode spin coating. Hasil pengamatan dengan atomic force microscopy menegaskan bahwa lapisan tipis tersusun dari struktur islands dengan dimensi nano meter orde. Dimensi lateral lapisan tipis dengan N = 3 menunjukkan struktur island sebesar 800 nm yang lebih kecil dibandingkan sampel N = 5 yaitu 1200 nm. Pengamatan lebih detail untuk skala scan lebih kecil menegaskan bahwa dimensi islands yang besar merupakan himpunan islands kecil-kecil membentuk suatu ikatan tertentu. Akhirnya, jika satu unit islands merupakan sebuah molekul, maka island-island tersebut berinteraksi membentuk suatu supra-molekuler. ABSTRACTSynthesis and fabrication of nanoparticle-based thin layer of natural porphyrin is reported in this paper. Porphyrin solution was synthesized by using a process of natural purification with column chromatography techniques. It was then grown into a thin film an a Cu substrate by spin coating method. Observations with atomic force microscopy confirmed that the thin layer structure is with the composition of islands with dimensions of the order of nano-meters. The lateral dimensions of the thin layer with N = 3 showed the structure of the island of 800 nm which is smaller than the sample of N = 5 is 1200 nm. Moreover, an observation of smaller-scale scan confirmed that the islands which are larger dimension are composed of small islands with a certain bond. Finally, if the one unit of island is a molecule, the islands may interact to form a supra-molecular.

Synthesis and fabrication of nanoparticle-based thin layer of natural porphyrin was reported in this paper. The natural porphyrin solutions used in the experiments were synthesized by using a process of column chromatography techniques. Then natural porphyrin thin films were deposited by spin coating methods on Cu substrate. Experiment result showed that natural porphyrin thin films composed of discrete islands. More detailed observation show that the islands were formed from smaller islands that called supra molecule.
