Porphine has a great potential application in molecular electronic devices. In this work, based on the density functional theory (DFT) and combining with nonequilibrium Green’s function (NEGF), we study the transport properties of the molecular devices constructed by the covalent homocoupling of porphine molecules conjunction with zigzag graphene nanoribbons electrodes. We find that different couple phases bring remarkable differences in the transport properties. Different coupling phases have different application prospects. We analyze and discuss the differences in transport properties through the molecular energy spectrum, electrostatic difference potential, local density of states (LDOS), and transmission pathway. The results are of great significance for the design of porphine molecular devices in the future.

“…Quinone derivatives are an important class of compounds for photosynthetic processes, and their characteristic response to light and energy-transfer properties have been extensively studied [28][29][30][31][32][33][34][35][36][37]. Moreover, they have been widely used as photoreactive materials for semiconductor manufacturing [38][39][40][41][42]. In contrast to these scientific and industrial applications of quinone derivatives, studies on the photoreactivity of aminobenzoquinones are limited, although several reports have been published on their photochemical cyclization [25,[43][44][45][46].…”

In this detailed study of the photoreaction of 2,5-bis(dibenzylamino)-3,6dichloro-p-benzoquinone, two new products were separated along with the previously reported debenzylated analogues, and their molecular structure was determined. One compound was identified as 2-(benzylamino)-3,6-dichloro-5-(dibenzylamino)-p-benzoquinone, which was found to undergo further debenzylation to form the two known debenzylated analogues. The 2 other compound was identified as the hydroquinone form of the starting material. This photoreaction was examined in detail using various analytical techniques under different experimental conditions, and a plausible reaction pathway was proposed on the basis of the experimental results. In addition, the reaction was found to occur also under sunlight irradiation.
