The Langmuir-Blodgett (LB) technique is a way of making supra-molecular assembly in ultrathin films with a controlled layered structure and crystal parameter, which have many envisioned technological applications for optical and molecular electronic devices as well as signal processing and transformation. Probably LB technique is the best method to manipulate materials at molecular level and provides a scope to realize the molecular electronics in reality. In this review article, we have discussed about the general introduction of LB technique and recent development on LB and related system including (i) LB methodology, (ii) characterizations of LB films, (iii) LB films and molecular electronics, (iv) historical review of LB films, (v) research and applications including fundamental research and application towards devices.

“…This work used a method involving the horizontal lifting of a Langmuir monolayer film onto a solid surface, a process called LS technique. The results indicated that the ordered LS monolayers exhibit a prominent PL that is better than that of polycrystalline devices (Figure c,d) . Controlled assembly of the n‐type organic semiconductor N , N ′‐1H,1H‐perfluorobutyl dicyanoperylenecarboxydiimide (PDIF‐CN 2 ) via the LB technique has also been reported.…”

the complex microstructures and undesir able qualities of conventional organic bulk thin films can largely lead to severe performance bottlenecks in functional OFETs [23,24] and serve as essential chal lenges in unveiling the intrinsic electrical properties. [25] Therefore, a new organic material is profoundly required to satisfy the anticipated demand for fundamental studies and to sustain the revolutionary advancement in organic electronics.As an emerging electronic material, 2D molecular crystals (2DMCs) have attracted particular attention since their discovery. [26,27] The material structure of 2DMC features a monolayer (ML) or few layers of molecules that are assembled via weak van der Waals (vDW) bonding along two dimensions. 2DMCs have also dem onstrated unique characteristics of thick ness uniformity over a large scale, perfect lateral continuity with an atomically flat surface, and longrange molecular ordering. Particularly, when the available conforma tions of crystalline molecular semiconductors are restricted under a special constraint geometry, the interlayer screening that commonly exists in the 3D bulk organic semiconducting crystals can be effectively eliminated. [27,28] Thus, 2DMCs are extremely fascinating for the direct exploration of the charge accumulation and transport behaviors regarding the properties of the semiconductor/insulator interface, disorder effects, and polaronic relaxation. Especially, in 2DMCbased FETs, the inter facial interactions on the molecular crystals can be well con fined at 2D limit, exhibiting different influences from layer to layer. Thus, the microscopic behaviors of charge carriers can be much effectively modulated. Therefore, 2DMCs possess unique optoelectronic properties that cannot be achieved in conven tional bulk molecular crystals. [29][30][31] Besides, utilizing their ultrathin structural features and superior interface qualities can significantly contribute to the enhanced performance of 2DMC based functional FETs. These unique merits, combined with intrinsic properties, such as lightweight construction, material versatility, and chemical/environment stability, explicitly enable these 2D crystals fascinating prospects for realistic applications in advanced electronic technologies. [15,[32][33][34][35] Obtaining molecular crystals with 2D morphology is an essential prerequisite for scientific and technological studies. Pioneering efforts have been devoted to vaporgrown 2DMCs. [36][37][38][39][40][41][42] However, the expensive preparation cost and rigorous growth conditions have rendered these methods Based on intensive research, organic field-effect transistors (OFETs) will likely remain at the zenith in information science for many years due to their numerous potential applications in portable and smart electronic devices. Elucidating the intrinsic charge-transport behavior and realizing functional OFETs with superior device characteristics have been the cornerstones for the sustainable advancement in organic electronics. The emerging 2D molecular crystal...

“…It is because molecular forces are strictly regulated in the process that the resulting films can be smooth and uniform in thickness, less affected by the uneven solvent evaporation at the interface. It should be noted that the Langmuir technique 117–120 and self‐assembly 64,121–123 are in the category of nanoadditive manufacturing, which is usually applied for fabricating monolayer OFET devices. As mentioned before, the extreme case of ultrathin films is a monolayer, and a number of examples given here in various fabrication methods are monolayer OFET‐based chemical sensors.…”

In the past decades, a variety of organic field‐effect transistor (OFET) based sensors have been reported, holding great promise in physical sensing, chemical sensing, biosensing, medical sensing and functionalized integrated sensor arrays, thanks to the superiorities of OFETs, including fabrication versatility and high sensitivity to external stimulus. However, the sensing performance still needs to be enhanced to meet practical application requirements, especially high sensitivity and short response time. Among all the effective strategies, ultrathin organic semiconductor (OSC) film devices show significantly promoted sensing performance, and the fabrication methods to obtain these ultrathin OSC films are of importance and diversity. Here, a brief review focused on ultrathin (including molecular monolayer) OSC film fabrication methods is presented, including high‐vacuum thermal evaporation, solution‐processable methods, and the approach of combining ultrathin films with heterojunctions. Additionally, applications of ultrathin OFET‐based chemical and biological sensors are summarized. Finally, the outlook and challenges ahead are discussed. We hope this review can offer guidance for the fabrication methods and potential applications of ultrathin OFET‐based chemical and biological sensors in the future. © 2020 Society of Industrial Chemistry
