Elaboration of PCDTBT nanorods and nanoflowers for augmented morphological and optical properties

Controlling the morphological, structural, and optical properties of one-dimensional PCDTBT nanotubes by template wetting

“…PCDTBT nanotubes prepared from 2 h of infiltration time have experienced 2 cm -1 of downward shift at the band that was assigned for C-S deformation. A band of C-H deformation has shown a downward shift of about approximately 3 cm -1 for PCDTBT nanotubes that were obtained from 24 h of immersion time, which has been previously reported elsewhere for PCDTBT nanostructures [7]. At the band assigned for C-C stretching of Cz segment (1,361 cm -1 ), no changes in the Raman shift were recorded by the PCDTBT nanotubes and thin films.…”

“…Poly [N-9′-heptadecanyl-2, 7-carbazole-alt-5, 5-(4′, 7′-di-2-thienyl-2′, 1′, 3′-benzothiadiazole)] (PCDTBT) is a promising p -type conjugated polymer that possesses exceptional electrical conductivity and optical properties [ 4 , 7 , 10 , 12 - 15 ]. These exceptional properties have attracted many researchers to utilize the PCDTBT thin film as an active layer in organic photovoltaic devices [ 10 , 12 , 13 ].…”

Formation of PCDTBT:PC71BM p–n junction composite nanotubes via a templating method

“…[1][2][3][4] These favourable properties are highly reliant on the preparation methods and the resulting nanostructures. 5,6 Nanostructures of conjugated polymers such as nanorods, nanowires, nanoowers and nanotubes [7][8][9] are some of the outstanding approaches in the development of versatile fabrications. The physical and chemical properties of polymers such as the degree of polymerization, molar mass distribution, crystallinity and intermolecular properties can be altered by varying the fabrication technique.…”

“…Poly[N-90-hepta-decanyl-2,7-carbazole-alt-5,5-(40,70-di-2thie-nyl 20,10,30 benzothiadiazole)] (PCDTBT) is the most promising p-type conjugated polymer that possesses outstanding structural, optical and electronic properties. 1,4,6,9,10 Recently, PCDTBT has been extensively used as an active layer by either incorporating it with n-type materials in a bulk heterojunction system or as a single nanostructured material. 6,9,11 The synthesis of the polymer composite at the nanoscale has received much attention.…”

“…1,4,6,9,10 Recently, PCDTBT has been extensively used as an active layer by either incorporating it with n-type materials in a bulk heterojunction system or as a single nanostructured material. 6,9,11 The synthesis of the polymer composite at the nanoscale has received much attention. Polymer composites that are composed of both p-and n-type materials have a potential to enhance the charge carrier separation, charge carrier transfer and light absorption due to the formation of a p-n junction.…”
