A novel design for porphyrin based D–s–A systems as molecular rectifiers

Abstract

Electro-grafted porphyrin-based D–s–A monolayers on Si behave as rectifiers.

Large-Area, Ensemble Molecular Electronics: Motivation and Challenges

“…A similar highly-doped Si, which is often considered as effectively metallic, was recently reported to yield RR of 10 6 -10 7 , when the molecular layer contained an active redox moiety (porphyrin), with Hg as a top contact. 388 These huge RR values for porphyrin-based monolayers must originate in a unique synergism between the molecules and the highly-doped Si. Indeed, the giant RR of 10 6 -10 7 was observed only if the porphyrin was tethered to the Si via 11 carbon long alkyl chains, while a 6 carbon tether yielded only RR ≤ 100.…”

An Ultrasensitive Organic Semiconductor NO2 Sensor Based on Crystalline TIPS‐Pentacene Films

“…For example, using thicker film can enhance the signals but accompanied by the loss of response/recovery speed, [10,30,31] while adopting current amplifying device like transistors would increase background current simultaneously. [9][10][11][12][13][14][15][16][17][18][19] However, the performance of most OSC sensors for oxidizing gases is not sufficient. [8,19,32] Moreover, directly using high conductivity OSC films with high mobility materials or heterostructures as active layers may not efficiently improve the sensitivity.…”

Crystal structure of chlorido(5,10,15,20-tetraphenylporphyrinato-κ4N)manganese(III) 2-aminopyridine disolvate

“…In a continuation of our studies of metalloporphyrins, which are usually used as models of hemoproteins and have various applications in many fields such as catalysis (Amiri et al, 2014), photodynamic therapy (Kolarova et al, 2005), conception of sensors (Garg et al, 2013) or the design of photoluminescent species (Harry et al, 2003), we report herein the synthesis and crystal structure of the title compound, [Mn(C 44 H 28 N 4 )Cl]Á2C 5 H 6 N 2 , (I).…”
