Preparation of large-area ultrathin carbon semiconductors converted from conjugated microporous polymer films

Abstract

Large-area carbon semiconductors were prepared by combining the in situ polymerization with thermal annealing process. Moreover, a photodetector based on carbon dots decorated carbon semiconductors was fabricated.

The rise of morphology-engineered microporous organic polymers (ME-MOPs): synthesis and benefits

“…While the conventional synthesis of MOPs resulted in the formation of irregular particulate materials, a significant formation of ME-MOPs has been reported in the literature. 20 a , b ,21–66 Usually, ME-MOPs have been prepared by template synthesis. 20 b ,21–37 However, in some cases, ME-MOPs could be obtained by non-template synthesis.…”

“…20 a , b ,21–66 Usually, ME-MOPs have been prepared by template synthesis. 20 b ,21–37 However, in some cases, ME-MOPs could be obtained by non-template synthesis. 38,39 Moreover, new synthetic approaches have been suggested for ME-MOPs.…”

“…4). 20 b ,21–34 The conventional shell thicknesses of H-MOPs were observed in the range of 5–40 nm. One of the most common hard templates in materials science is silica materials.…”

“…6). 31–34 At first, thin layered silica plates could be used as templates for the formation of MOP layers on their surface. 31 a The etching of silica layers induced the formation of MOP films (MOPF-1) (Fig.…”

“…3). 20 b ,21–37 Moreover, the template-free synthesis of ME-MOPs could also be found in the literature. 38,39 In addition, unprecedented synthetic approaches have recently emerged for ME-MOPs, such as the synthesis of ME-MOPs utilizing ME-MOPs 40–42 and noncovalent–covalent double assembly.…”
