Thiophene-based molecular and polymeric semiconductors for organic field effect transistors and organic thin film transistors

Recent advances in the application of isoindigo derivatives in materials chemistry

“…The advantages of organic oligomeric and polymeric materials for applications in OFET and thin-film transistor (TFT) technologies are due to the ease of their directed chemical modification, mechanical flexibility, the possibility of varying optoelectronic properties, and good solubility in a wide range of solvents [59][60][61]. In this regard, the most studied and promising are π-conjugated polymer structures based on sulfur, oxygen, nitrogen, and selenium heterocyclic compounds [62,63]. One of the systems for creating OFET devices is the isoindigo platform [64][65][66][67][68].…”

New thiophene-based conjugated macrocycles for optoelectronic applications

“…Small molecules and polymers used as active components of organic electronics have received a very high level of attention in recent decades owing to their wide range of attractive features including solution processability, tunable absorption and energy levels, high carrier mobility, and photochemical and thermal stability. [1][2][3][4][5][6][7][8][9] Several devices have evolved through the use of these materials, such as field-effect transistors (FETs) for microelectronics, 10,11 light-emitting diodes (LEDs) for lighting and displays, [12][13][14][15] sensors, [16][17][18] lasers, [19][20][21] molecular switches [22][23][24] and photovoltaics. [25][26][27][28][29][30][31] Despite the tremendous achievements in recent years that have led to the commercialisation of these devices, significant efforts are still devoted to enhance their performance, improve their processability and stability and understand their functionality.…”

Approaching the Integer‐Charge Transfer Regime in Molecularly Doped Oligothiophenes by Efficient Decarboxylative Cross‐Coupling

“…Thiophene based-materials have attracted at remendous amount of attention in recent decades. [1,2] Among them, pconjugated poly/oligothiophene have been at the center of focus owing to their applicability as organic electronic materials in organic photovoltaic cells (OPVCs), [1][2][3][4] organic light emitting diodes (OLEDs), [2][3][4] organic field-effect transistors (OFETs), [1,5] liquid crystals, [6] and fluorescent biomarkers. [7] In electronic applications,c onjugated organic molecules and polymers are employed as organic semiconductors (OSCs) and, in analogy to their inorganic counterparts,e lectrical doping is frequently employed to tune both their conductivity and electronic structure to meet application-specific demands.…”
