“…In the past decades, synthesis of π‐extended porphyrins has attracted immense interest for their unique optical and electronic properties which render them highly valuable for a variety of applications, for example, as near‐infrared (NIR) dyes, organic semiconductors, and nonlinear optical materials . Various aromatic hydrocarbons, including benzene, naphthalene, pyrene, azulene, corannulene and coronene, have thus been fused to the meso‐ and β‐positions of the porphyrin.…”

Two unprecedented porphyrin fused nanographene molecules, 1 and 2, have been synthesized by the Scholl reaction from tailor‐made precursors based on benzo[m]tetraphene‐substituted porphyrins. The chemical structures were validated by a combination of high‐resolution matrix‐assisted laser desorption/ionization time‐of‐flight mass spectrometry (HR MALDI‐TOF MS), IR and Raman spectroscopy, and scanning tunnelling microscopy (STM). The UV‐vis‐near infrared absorption spectroscopy of 1 and 2 demonstrated broad and largely red‐shifted absorption spectra extending up to 1000 and 1400 nm, respectively, marking the significant extension of the π‐conjugated systems.

“…Ni, Co, Cu, Zn, Pt, and Mn. [1][2][3][4][5] For instance, various applications of porphyrin-related materials, such as the light-absorbing components in dye sensitized solar cells [6][7][8][9] , active layers for organic thin film transistors [10][11] , and multi-functional sensors [12][13][14] , have been developed. Previous studies have been reported the porphyrin metalation involving the coordination with post-or pre-deposited metal atoms on well-defined metal or metal oxide substrate [15][16][17][18][19][20][21] or vapor phase-metalation by atomic layer deposition process.…”

A Surface Chemical Reaction in Organic–Inorganic Materials Using a New Chemical Evaporation System

We report the surface reaction that occurs in organic-inorganic thin films using a hybrid deposition system that combines thermal evaporation (TE) and metalation process. Growth of a smooth, uniform organic-inorganic hybrid thin film was demonstrated, and the occurrence of a self-limited surface reaction between the organic semiconductor and the inorganic metal atom during metalation process was confirmed with X-ray photoelectron spectroscopy (XPS) and Raman analysis. In this study, we utilized a hybrid deposition system that combined TE and vapor phase-metalation to create an organic-inorganic hybrid thin film. Experimental data and theoretical simulation of a model system are also provided to explain the barrierless reaction that occurs during synthesis of a zinc tetraphenyl porphyrin (ZnTPP) thin film. This process can be utilized to increase the flexibility for the advanced synthesis of organic-inorganic hybrid thin films.

“…Actually, the nature of the central metal and the lateral groups are responsible for the sensor properties. For instance, the porphyrins with different central atoms (Zn, Ni and Cu) and lateral groups are studied for sensor application by Saleem et.al [15], Sayyad et.al [16] and Ahmad et.al [18]. These studies show that with only a little variation in synthesis, it is possible to obtain sensors with different sensitivity and responses.…”

Organic semiconductor-based solar photovoltaic cells and sensors are scalable, printable, solution processable, bendable and light-weight. Furthermore, organic semiconductors require low energy fabrication process, hence can be fabricated at low cost as light-weight solar cells and sensors, coupled with the ease of processing, as well as compatibility, with flexible substrates. Organic semiconductors have been identified as a fascinating class of novel semiconductors that have the electrical and optical properties of metals and semiconductors. The continuous demand to improve the properties of organic semiconductors raises the quest for a deep understanding of fundamental issues and relevant electronic processes. Organic semiconductor thin film is sandwiched between two metal electrodes of indium tin oxide (ITO) and aluminum to form organic photovoltaic solar cell. Several types of organic semiconductors have been utilized as the photoactive layer in the solution processable organic solar cells. The performance of the fabricated solar cells can be improved by dissolving the material in the right choice of solvent, annealing of organic thin film, slowly forming the thin film and introducing an infra-red absorbance layer. Besides, organic semiconductor-based sensors can be fabricated utilizing either in a sandwidch type or planar type device. Some of these techniques and the experimental results are presented.
