The phrase "accepting unit" is correct and usable in written English.
It can be used in contexts where you are referring to a unit or entity that is designated to accept something, such as payments, items, or information.
Example: "The accepting unit for this transaction is located at the front desk, where you can submit your documents."
Alternatives: "receiving unit" or "designated unit".
Three novel donor-acceptor polymers have been synthesized with Suzuki cross-coupling between thiophenyl-methylene-9H-fluorene donating unit with thiazolo[5,4-d]thiazole (PFTTTz), benzothiadiazole (PFTODTBT) or [1,2,3]triazolo[4,5-g]quinoxaline (PFTDTBTzQ) accepting unit.
Structure affinity relationships (SARs) of non-peptide CRF1 antagonists suggest that such antagonists can be constructed of three units: a hydrophobic unit (Up-Area), a proton accepting unit (Central-Area), and an aromatic unit (Down-Area).
Two regioisomeric π-conjugated terpolymers bearing carboxylated thiophene (CT) as electron accepting unit and thienothiophene (TT) and bithiophene (BT) as electron donating units were successfully synthesized for enhancing the performance of polymer solar cells (PSCs).
Here, we designed and synthesized two types of medium bandgap polymers in which two dimension-conjugated benzodithiophene (BDT BDTTTT and BDTPS) was used as the electron donating units and tetrafluoroquinoxaline (ffQx) was used as electron accepting unit, namely PffQx-T and PffQx-PS, for the application as donor in the PSCs with a popular non-fullerene small molecule ITIC as acceptor.
The presence of alternating electron-donating and accepting units results in a donor-acceptor-donor architecture of these molecular systems.
Non-planar unit triphenylamine (TPA) was copolymerized with accepting units, isoindigo (IIG) or naphthalene diimide (NDI), to afford three non-planar conjugated polymers.
A combination of aggregation-induced emission and intramolecular charge transfer was achieved by using a triphenylamine analogue and a dicyanovinyl moiety as the electron donating and accepting units, respectively.
Comparison with calculated electronic structure shows that the construction of chromophores that consist of electron donating and accepting units does not always follow the simple rules that are generally used in the design of such molecules.
Compared to bare hydrogen-attached 4 with triplet energy (T1) of 2.7 eV, the conjugated moiety based 1 and 6 lowered T1 to ≤2.50 eV, while other compounds bearing either non-conjugated donating or accepting units unexpectedly maintain T1 as high as ∼2.70 eV.
These sequence motifs suggest that including new heterocycles with H-bond accepting units at the appropriate position in the diamidine derivatives could provide G·C bp recognition capability in the AT sequence context.
For comparison purposes, let's look at everything in the widely accepted unit of meters.
