Problems solved by technology

[0015] Disadvantageously, the crystallinity of the resulting 2D polymers remains unsatisfactory with small domain sizes (typically tens of nanometers), which poses a potential limitation to the development of reliable functionalities for this emerging class of organic 2D materials.

Embodiment Construction

[0122] Formation of surfactant monolayers

[0123] Dissolve 20 μL of sodium oleyl sulfate (SOS) (1 mg ml in chloroform) -1 ) on the surface of 100 ml of Milli-Q water in a 200 ml beaker. The average molecular area (mma) is It can be calculated by the following formula:

[0124]

[0125] In the formula, Ae=25.12cm 2 , is the effective area; M w =M w,sos =370.5g mol -1 , is the molecular weight of SOS; Na=6.02×10 23 mol -1 is Avogadro's constant; m=m sos = 20 μg, which is the mass of the surfactant. The mma allows SOS molecules to form monolayers such as Figure 3A confirmed by the π-A isotherm in .

[0126] Similar to SOS, 15 μl stearic acid (SA, 1 mg ml in chloroform -1 ) was distributed at the interface between air and 100 ml of Milli-Q water. mma is allows SA molecules to form monolayers such as Figure 3B confirmed by the π-A isotherm in .

Abstract

The present invention relates to a method for synthesizing a two-dimensional or quasi-two-dimensional polymer comprising a surfactant, a two-dimensional or quasi-two-dimensional polymer film and use for producing a film, an electronic device or a catalyst.

Description

technical field [0001] The present invention relates to a method for synthesizing two-dimensional or quasi-two-dimensional polymers comprising surfactants, two-dimensional or quasi-two-dimensional polymer membranes and their use for the production of membranes, electronic devices or catalysts. Background technique [0002] Both synthetic and natural polymers play an important and ubiquitous role in our everyday life, and according to the definition proposed by Hermann Staudinger in the early 1920s (Staudinger 1920), they can often be linked linearly by covalent bonds. The repeating unit sequence is described. [0003] There have been numerous attempts to go beyond Staudinger's concept to synthesize sheet polymers with long-range order along two orthogonal directions, namely two-dimensional (2D) polymers, which can be traced back to Gee's interfacial polymerization experiment in 1935 (Gee 1935) , 1958 Blumstein cross-linked polymers in the interlayer space of smectite clays ...
