Fig. 9. Nanoparticles prepared by living CDSA for applications in optoelectronics. (A) Schematic illustration of PFDMS-based fiber-like micelle growth across an electrode gap by living CDSA from chemisorbed seed micelles. AFM height micrograph (1) highlighting a 7.7 nm high (2) nanofiber spanning two gold electrodes. (B) Device schematic and AFM micrograph (1) of an organic field effect transistor utilizing P3HT BCP nanofibers as the active layer. A plot of saturation mobility against fiber length (2) shows a superlinear relationship. (C) B–A–B fiber-like micelles with PDHF core and a PEG and quaternized polythiophene (QPT) segmented corona. Normalised absorption and emission for PDHF and QPT (1) showing energy overlap between the PDHF emission and QPT absorption which allows for energy transfer. Laser scanning confocal microscopy image of the B–A–B micelles (2), blue = PDHF emission, orange = QPT emission. (D) Schematic illustration of PPV-b-P2VP self-assembly to produce 2D platelet micelles as imaged by TEM (1). Current-force characteristics (2) of a flexible pressure sensing tunnelling device (inset picture) containing a PPV-based platelet micelles with different bending radii.
