The phrase "attached electron" is correct and usable in written English.
It can be used in scientific contexts, particularly in chemistry or physics, to refer to an electron that is bound to an atom or molecule.
Example: "In the process of ionization, an atom can lose an attached electron, resulting in a positively charged ion."
Alternatives: "bound electron" or "associated electron".
In contrast, the lower electron density of azo dyes attached electron-withdrawing substituents [i.e., halogen (–X), nitro group (–NO2), carboxyl group (–COOH) or sulfonate (–SO3 −)] was more easily reductively decolorized.
So it was rational to attach electron donating atoms in these side chains.
Additionally, an inverse linear correlation between electron affinity of the matrix and beam current is observed, suggesting that the propensity of the metal matrix to attach electrons impacts the ion signal.
The hydrogen-bonding ability of the urea was further enhanced by attaching electron-withdrawing 3,5-bis trifluoromethyl benzyl groups.
In addition it is evident that N-C-Ar carbon, in all cases, is more deshielded as compared to N-C-R carbon due to being sandwiched by two electron withdrawing groups because N-C-R group is attached to electron withdrawing and donor groups (Figure 4). Figure 4 Relative deshielding of methylene groups, attached directly to benzimidazolium units in NMR spectroscopy.
Structure-Activity relationships (SAR) based on the obtained results indicated that the best observed antibacterial activity is that which Ar is phenyl ring attached with electron donating function (MeO) as exhibit in compound 6n.
Structure-Activity relationships (SAR) based on the obtained results indicated that the best observed antifungal activity is that which Ar is phenyl ring attached with electron withdrawing function (NO2, Cl) as exhibit in compound 6l and 6d, respectively.
On the basis of combined results from FT-IR and Raman spectra, it could be tentatively concluded that TMPBA had been attached to electron deficient SWCNTs via "direct" Friedel Crafts acylation reaction to give TMPBA-g-SWCNT and SWCNTs could be further purified in the reaction medium.
Highly efficient and thermally stable nonlinear optical chromophores based on the same thiophene π-conjugation and tricyanofuran acceptor (TCF) possessing different isolation groups attached to electron-donating moiety have been synthesized and systematically investigated in this paper.
