Tailoring the self-assembled structures and photonic properties of organic nanomaterials

Abstract

Organic nanomaterials have attracted more and more attention for their applications in nano-photonics due to their high photoluminescence quantum efficiencies, color tunabilities, and size-dependent optical properties. With the distinctive features of photoluminescence, waveguiding and dimensional confinement, different organic nanostructures, such as 0D nanoparticles, 1D nanowires and 2D nanosheets, have a significant influence on their photonic properties. Therefore, it is of great importance and scientific interest to develop the strategy for tailoring the self-assembled structures with specific photonic behaviors in desired manners. In this mini review, we give a brief review of the recent work on the control of self-assembled organic nanostructures, and the tunable photonic properties of the predetermined structures.

“…Self-Assembled 1D Nanofibers of PIs (As Listed in Figure 26) nation. 28,126,148 Such efficient charge transfer can also be found in organic/inorganic hybrid D−A nanostructures, for instance, PDI/ZnS/CdSe and PDI/CdS. 149−151 On the other hand, wellordered organic/inorganic or organic/organic interfaces, as shown in Figure 28c−i, are very important for organic electronic and optoelectronic devices.…”

Self-assembly of tetraalkoxydinaphthophenazines in monolayers on HOPG by scanning tunneling microscopy

“…In addition to strictly defined conditions of thermodynamical nature such as their reduction and oxidation potentials [7,8], the organic semiconductors suitable for the applications in highly performing devices should meet several requirements concerning their capability of forming ordered supramolecular structures in thin films and monolayers, possibly via self-assembly [9][10][11][12][13][14][15][16][17]. Thus self-assembly of conjugated molecules is one of the crucial factors which influence or even determine the electrical transport properties in organic semiconductors.…”

Poly(3-hexylthiophene) Nanoparticles Containing Thiophene-S,S-dioxide: Tuning of Dimensions, Optical and Redox Properties, and Charge Separation under Illumination

“…Indeed, nanoparticles based on conjugated polymers are emerging as multifunctional nanoscale materials that promise great potentials. [27][28][29][30][31][32][33] Here we report that the use of Rozen's reagent, one of the most powerful oxygen transfer agents, [8][9][10][11] allows for the preparation of poly(3-hexylthiophene-S,S-dioxide) nanoparticles, whose properties can be skillfully tuned through the controlled introduction of TDO moieties before or after the formation of poly(3-hexylthiophene) nanoparticles. The different modalities of introduction of TDO moieties causes the formation of either PTDO-NPs obtained from pre-oxygenated P3HT, with dimensions down to 5 nm, or core-shell P3HT@PTDO-NPs obtained from oxygenation of the surface of preformed P3HT nanoparticles.…”
