Organic semiconductors for biological sensing

Abstract

In this review, we provide an overview of conjugated organic semiconductors and their applications in biological sensing with a primary focus on the role of the organic semiconductor.

Glycolated Thiophene‐Tetrafluorophenylene Copolymers for Bioelectronic Applications: Synthesis by Direct Heteroarylation Polymerisation

“…Semiconducting materials are an essential ingredient for the research and development of new, more efficient organic electronic devices such as organic light‐emitting diodes (OLEDs), organic photovoltaic cells (OPV), organic field‐effect transistors (OFETs), and also for the quickly evolving field of organic bioelectronics . Several successes have been achieved in the bioelectronics field, such as measuring neural activity, direct metabolite detection, controlling epileptiform activity or electrophoretic drug delivery .…”

Carbazole‐Terpyridine Donor‐Acceptor Dyads with Rigid π‐Conjugated Bridges

“…Product (5) was collected by filtration of the solution as a white solid in 30 % yield (16.2 mg). 1 9-((4-((4-([2,2':6',2''-terpyridin]-4'-yl)phenyl)ethynyl) phenyl)ethynyl)-9H-carbazole (6). In a Schlenk flask, Pd(PPh 3 ) 2 Cl 2 (40.3 mg, 0.06 mmol) and CuI (11.0 mg, 0.06 mmol) were added to a solution of ((4-bromophenyl)ethynyl)trimethylsilane (17 (19) (93.2 mg, 0.30 mmol)in anhydrous THF (7 mL).…”

“…Expanding our previous approach to the preparation of Cbz-Tpy dyads such as 1 and 2 (Figure 1), we have designed and synthesized five new carbazole-terpyridine derivatives (3)(4)(5)(6)(7), in which the π-conjugated bridge between the donor and acceptor units is progressively elongated with acetylene, phenylene and even anthracene units.…”

“…Organic conjugated systems exhibit wide interest as functional materials in several applications . They are generally easy to prepare at low‐cost and their electronic and optical properties can be predicted to a good extent, therefore displaying remarkable advantages over inorganic materials.…”

“…Organic conjugated systems exhibit wide interest as functional materials in several applications. [1][2][3][4][5][6][7] They are generally easy to prepare at low-cost and their electronic and optical properties can be predicted to a good extent, therefore displaying remarkable advantages over inorganic materials. Accordingly, they are extensively used as active layers in a variety of organic devices, such as light-emitting diodes (OLEDs), [8] field-effect transistors (OFETs), [9] photovoltaic cells (OPVC), [5,10,11] dye-sensitized solar cells (DSSC), [12] sensors [13,14] as well as in bioimaging applications.…”
